Allow environment variables to be hidden (#3950)
* Allow environment variables to be hidden

This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.

Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.

This is a workaround for issues like #3920.

Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.

One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.

An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.

Allow custom lib dir path for sourcing nu script libraries. (#3940)
Given we can write nu scripts. As the codebase grows, splitting into many smaller nu scripts is necessary.

In general, when we work with paths and files we seem to face quite a few difficulties. Here we just tackle one of them and it involves sourcing
files that also source other nu files and so forth. The current working directory becomes important here and being on a different directory
when sourcing scripts will not work. Mostly because we expand the path on the current working directory and parse the files when a source command
call is done.

For the moment, we introduce a `lib_dirs` configuration value and, unfortunately, introduce a new dependency in `nu-parser` (`nu-data`) to get
a handle of the configuration file to retrieve it. This should give clues and ideas as the new parser engine continues (introduce a way to also know paths)

With this PR we can do the following:

Let's assume we want to write a nu library called `my_library`. We will have the code in a directory called `project`: The file structure will looks like this:

```
project/my_library.nu
project/my_library/hello.nu
project/my_library/name.nu
```

This "pattern" works well, that is, when creating a library have a directory named `my_library` and next to it a `my_library.nu` file. Filling them like this:

```

source my_library/hello.nu
source my_library/name.nu
```

```

def hello [] {
  "hello world"
}
```

```

def name [] {
  "Nu"
end
```

Assuming this `project` directory is stored at `/path/to/lib/project`, we can do:

```
config set lib_dirs ['path/to/lib/project']
```

Given we have this `lib_dirs` configuration value, we can be anywhere while using Nu and do the following:

```
source my_library.nu

echo (hello) (name)

```

The zip command. (#3919)
We introduce it here and allow it to work with regular lists (tables with no columns) as well as symmetric tables. Say we have two lists and wish to zip them, like so:

```
[0 2 4 6 8] | zip {
  [1 3 5 7 9]
} | flatten

───┬───
 0 │ 0
 1 │ 1
 2 │ 2
 3 │ 3
 4 │ 4
 5 │ 5
 6 │ 6
 7 │ 7
 8 │ 8
 9 │ 9
───┴───
```

In the case for two tables instead:

```
[[symbol]; ['('] ['['] ['{']] | zip {
  [[symbol]; [')'] [']'] ['}']]
} | each {
  get symbol | $'($in.0)nushell($in.1)'
}

───┬───────────
 0 │ (nushell)
 1 │ [nushell]
 2 │ {nushell}
───┴───────────
```

Rustyline bug fixes (#3916)
* Mitigate history file bug in Rustyline

Rustyline's duplicate ignoring code has a bug that can cause data loss and
history file corruption. Testing seems to indicate that disabling this behavior
and allowing duplicates will prevent the bug from showing up. Many people have
complained about this issue, I think it is worthwhile to fix the bug at the cost
of permitting duplicate history entries.

Upstream bug: https://github.com/kkawakam/rustyline/issues/559

* Increase Rustyline historyfile limit

Rustyline will only store 100 history items by default. This is quite a small
limit for a shell that people use as a daily driver. Especially when the
deduplication code is removed, we will hit that limit quickly and start to lose
history. This commit bumps the limit up to 10k. We can discuss if this is an
inappropriate limit or if we should allow users to specify this setting in their
nushell config file instead.

Flexible dropping of rows (by desired row number) (#3917)
We very well support `nth 0 2 3 --skip 1 4` to select particular rows and skip some using a flag. However, in practice we deal with tables (whether they come from parsing or loading files and whatnot) where we don't know the size of the table up front (and everytime we have these, they may have different sizes). There are also other use cases when we use intermediate tables during processing and wish to always drop certain rows and **keep the rest**.

Usage:

```
... | drop nth 0
... | drop nth 3 8
```

Reimplement parsers with nu-serde (#3880)
The nu-serde crate allows us to become much more generic with respect to how we
convert output to `nu-protocol::Value`s. This allows us to remove a lot of the
special-case code that we wrote for deserializing JSON values.

Add the nu-serde crate (#3878)
* Add the nu-serde crate

nu-serde is a crate that can be used to turn a value implementing
`serde::Serialize` into a `nu-protocol::Value`. This has the potential to
significantly simplify plugin authorship.

This crate was the previously independent
[serde-nu](https://github.com/lily-mara/serde-nu) but the nushell maintainers
expressed an interest in having it added to the mainline nushell repository.

Support equals sign in shorthand environment variable values (#3869)
Some environment variables, such as `RUST_LOG` include equals signs. Nushell
should support this in the shorthand environment variable syntax so that
developers using these variables can control them easily. We accomplish this by
swapping `std::str::split` for `std::str::splitn`, which ensures that we only
consider the first equals sign in the string instead of all of them, which we
did previously.

Closes #3867
