Move 'where' to parser keywords; Add 'filter' command (#7365)
# Description

This PR moves the `where` command to a parser keyword. While it still
uses the shape-directed parsing dictated by the signature, we're free to
change the parsing code now to a custom one once we remove the syntax
shapes.

As a side effect, the `where -b` flag was removed and its functionality
has moved to the new `filter` command.

Just FYI, other commands that take row conditions:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`

We can either move these to the parser as well or make them accept a
closure instead of row condition.

# User-Facing Changes

New `filter` command which replaces `where -b` functionality.

$env.config now always holds a record with only valid values (#7309)
# Description
Closes #7059. Rather than generate a new Record each time $env.config is
accessed (as described in that issue), instead `$env.config = ` now A)
parses the input record, then B) un-parses it into a clean Record with
only the valid values, and stores that as an env-var. The reasoning for
this is that I believe `config_to_nu_record()` (the method that performs
step B) will be useful in later PRs. (See below)

As a result, this also "fixes" the following "bug":
```
〉$env.config = 'butts'
$env.config is not a record
〉$env.config
butts
```
~~Instead, `$env.config = 'butts'` now turns `$env.config` into the
default (not the default config.nu, but `Config::default()`, which
notably has empty keybindings, color_config, menus and hooks vecs).~~

This doesn't attempt to fix #7110. cc @Kangaxx-0

Reduced LOC by replacing several instances of Value::Int {}, Value::Float{}, Value::Bool {}, and Value::String {} with Value::int(), Value::float(), Value::boolean() and Value::string() (#7412)
# Description

While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
  val: a,
  span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

Add OneOf shape to fix else (#7385)
# Description

fixes #7384 

This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

# User-Facing Changes

`else` block will no longer capture variables as it will now use a block
instead of a closure.

Improve empty pipelines (#7383)
# Description

This fix changes pipelines to allow them to actually be empty. Mapping
over empty pipelines gives empty pipelines. Empty pipelines immediately
return `None` when iterated.

This removes a some of where `Span::new(0, 0)` was coming from, though
there are other cases where we still use it.

Allow $env and mutable records to be mutated by = (closes #7110) (#7318)
# Description

Closes #7110. ~~Note that unlike "real" `mut` vars, $env can be deeply
mutated via stuff like `$env.PYTHON_IO_ENCODING = utf8` or
`$env.config.history.max_size = 2000`. So, it's a slightly awkward
special case, arguably justifiable because of what $env represents (the
environment variables of your system, which is essentially "outside"
normal Nushell regulations).~~
EDIT: Now allows all `mut` vars to be deeply mutated using `=`, on
request.

Protocol: debug_assert!() Span to reflect a valid slice (#6806)
Also enforce this by #[non_exhaustive] span such that going forward we
cannot, in debug builds (1), construct invalid spans.

The motivation for this stems from #6431 where I've seen crashes due to
invalid slice indexing.

My hope is this will mitigate such senarios

Handle ctrl-c in RawStream iterator (#7314)
Fixes #7246 and #1898.

Darren noticed that `open /dev/random` could not be interrupted by
`ctrl+c`. Thankfully the solution was very simple; it looks like we just
forgot to check `ctrlc` in the `impl Iterator for RawStream`!

To reproduce this, just run `open /dev/random` and then cancel it with
`ctrl+c`.

Rename $env.config.explore_config to $env.config.explore (for consistency with $env.config.ls, $env.config.table etc.) (#7317)
# Description

* `$env.config.explore_config` renamed to `$env.config.explore`. This
follows the principle that config subrecords relating to single commands
(as this relates to `explore`) should be exactly named after the command
(see `ls`, `rm`, `table` etc.)
* In `into_config()`, moved the match arm relating to
`$env.config.explore` out of the "legacy options" section (which is
slated for removal in a later version).

[MVP][WIP] less like pager (#6984)
Run it as `explore`.

#### example

```nu
ls | explore
```

Configuration points in `config.nu` file.
```
  # A 'explore' utility config
   explore_config: {
     highlight: { bg: 'yellow', fg: 'black' }
     status_bar: { bg: '#C4C9C6', fg: '#1D1F21' }
     command_bar: { fg: '#C4C9C6' }
     split_line: '#404040'
     cursor: true
     # selected_column: 'blue'
     # selected_row: { fg: 'yellow', bg: '#C1C2A3' }
     # selected_cell: { fg: 'white', bg: '#777777' }
     # line_shift: false,
     # line_index: false,
     # line_head_top: false,
     # line_head_bottom: false,
   }
```

You can start without a pipeline and type `explore` and it'll give you a
few tips.

![image](https://user-images.githubusercontent.com/343840/205088971-a8c0262f-f222-4641-b13a-027fbd4f5e1a.png)

If you type `:help` you an see the help screen with some information on
what tui keybindings are available.

![image](https://user-images.githubusercontent.com/343840/205089461-c4c54217-7ec4-4fa0-96c0-643d68dc0062.png)

From the `:help` screen you can now hit `i` and that puts you in
`cursor` aka `inspection` mode and you can move the cursor left right up
down and it you put it on an area such as `[table 5 rows]` and hit the
enter key, you'll see something like this, which shows all the `:`
commands. If you hit `esc` it will take you to the previous screen.

![image](https://user-images.githubusercontent.com/343840/205090155-3558a14b-87b7-4072-8dfb-dc8cc2ef4943.png)

If you then type `:try` you'll get this type of window where you can
type in the top portion and see results in the bottom.

![image](https://user-images.githubusercontent.com/343840/205089185-3c065551-0792-43d6-a13c-a52762856209.png)

The `:nu` command is interesting because you can type pipelines like
`:nu ls | sort-by type size` or another pipeline of your choosing such
as `:nu sys` and that will show the table that looks like this, which
we're calling "table mode".

![image](https://user-images.githubusercontent.com/343840/205090809-e686ff0f-6d0b-4347-8ed0-8c59adfbd741.png)

If you hit the `t` key it will now transpose the view to look like this.

![image](https://user-images.githubusercontent.com/343840/205090948-a834d7f2-1713-4dfe-92fe-5432f287df3d.png)

In table mode or transposed table mode you can use the `i` key to
inspect any collapsed field like `{record 8 fields}`, `[table 16 rows]`,
`[list x]`, etc.

One of the original benefits was that when you're in a view that has a
lot of columns, `explore` gives you the ability to scroll left, right,
up, and down.

`explore` is also smart enough to know when you're in table mode versus
preview mode. If you do `open Cargo.toml | explore` you get this.

![image](https://user-images.githubusercontent.com/343840/205091822-cac79130-3a52-4ca8-9210-eba5be30ed58.png)

If you type `open --raw Cargo.toml | explore` you get this where you can
scroll left, right, up, down. This is called preview mode.

![image](https://user-images.githubusercontent.com/343840/205091990-69455191-ab78-4fea-a961-feafafc16d70.png)

When you're in table mode, you can also type `:preview`. So, with `open
--raw Cargo.toml | explore`, if you type `:preview`, it will look like
this.

![image](https://user-images.githubusercontent.com/343840/205092569-436aa55a-0474-48d5-ab71-baddb1f43027.png)

chrono version update

# Description

upgrade chrono to 0.4.23

# Major Changes

If you're considering making any major change to nushell, before
starting work on it, seek feedback from regular contributors and get
approval for the idea from the core team either on
[Discord](https://discordapp.com/invite/NtAbbGn) or [GitHub
issue](https://github.com/nushell/nushell/issues/new/choose).
Making sure we're all on board with the change saves everybody's time.
Thanks!

# Tests + Formatting

Make sure you've done the following, if applicable:

- Add tests that cover your changes (either in the command examples, the
crate/tests folder, or in the /tests folder)
- Try to think about corner cases and various ways how your changes
could break. Cover those in the tests

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace --features=extra -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect` to check that you're
using the standard code style
- `cargo test --workspace --features=extra` to check that all tests pass

# After Submitting

* Help us keep the docs up to date: If your PR affects the user
experience of Nushell (adding/removing a command, changing an
input/output type, etc.), make sure the changes are reflected in the
documentation (https://github.com/nushell/nushell.github.io) after the

Add logical xor operator (#7242)
We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.

Operator precedence

`and` > `xor` > `or`

Added logic and precedence tests.

It also converts dates into record but I couldn't get the test harness
to accept an example.

Thanks to @WindSoilder for writing the "hard" parts of this. :)

Clean up keyword lines in help (#7243)
# Description

This makes the help messages cleaner for keyword-style arguments.

Before:
```
  (optional) else_expression <Keyword([101, 108, 115, 101], Expression)>: expression or block to run if check fails
```

Now:
```
  (optional) "else" + <expression>: expression or block to run if check fails

New commands: break, continue, return, and loop (#7230)
# Description

This adds `break`, `continue`, `return`, and `loop`.

* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)

Examples:
```
for i in 1..10 {
    if $i == 5 {
       continue
    } 
    print $i
}
```

```
for i in 1..10 {
    if $i == 5 {
        break
    } 
    print $i
}
```

```
def foo [x] {
    if true {
        return 2
    }
    $x
}
foo 100
```

```
loop { print "hello, forever" }
```

```
[1, 2, 3, 4, 5] | each {|x| 
    if $x > 3 { break }
    $x
}
```

Make external command substitution works friendly(like fish shell, trailing ending newlines) (#7156)
# Description

As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.

And if the command is executed directly like: `cat tmp`, the result
won't change.

Fixes: #6816
Fixes: #3980


Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.

If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Stdout/Stderr redirection (#7185)
This adds new pipeline connectors called out> and err> which redirect either stdout or stderr to a file. You can also use out+err> (or err+out>) to redirect both streams into a file.

Make json require string and pass around metadata (#7010)
* Make json require string and pass around metadata

The json deserializer was accepting any inputs by coercing non-strings
into strings. As an example, if the input was `[1, 2]` the coercion
would turn into `[12]` and deserialize as a list containing number
twelve instead of a list of two numbers, one and two. This could lead
to silent data corruption.

Aside from that pipeline metadata wasn't passed aroud.

This commit fixes the type issue by adding a strict conversion
function that errors if the input type is not a string or external
stream. It then uses this function instead of the original
`collect_string()`. In addition, this function returns the pipeline
metadata so it can be passed along.

* Make other formats require string

The problem with json coercing non-string types to string was present in
all other text formats. This reuses the `collect_string_strict` function
to fix them.

* `IntoPipelineData` cleanup

The method `into_pipeline_data_with_metadata` can now be conveniently
used.

Limited mutable variables (#7089)
This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.

Mutable variables allow mutation via the assignment operator (=).

❯ mut x = 100
❯ $x = 200
❯ print $x
200

Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:

❯ mut x = 123; {|| $x }
Error: nu::parser::expected_keyword (link)

  × Capture of mutable variable.

The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.

Mutation can occur with fields as well, as in this case:

❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y

On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.

Removes 2 crates and should remove an unnecessary intra-workspace
dependency which might open up further opportunities for compilation.

* Make windows-only dependency conditional in toml

`omnipath` is only used on Windows and already behind a `#[cfg]` block
in the code. Made the dependency in `Cargo.toml` conditional as well.

* Make `nu-pretty-hex` example a proper example

This allows making `rand` a dev-dependency in this crate.
