Improves commands that support range input (#13113)
# Description
Fixes: #13105
Fixes: #13077

This pr makes `str substring`, `bytes at` work better with negative
index.

And it also fixes the false range semantic on `detect columns -c` in
some cases.

# User-Facing Changes
For `str substring`, `bytes at`, it will no-longer return an error if
start index is larger than end index. It makes sense to return an empty
string of empty bytes directly.

### Before
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #23:1:10]
 1 │ ("aaa" | str substring 2..-3) == ""
   ·          ──────┬──────
   ·                ╰── End must be greater than or equal to Start
 2 │ true
   ╰────

# bytes at
❯ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #27:1:25]
 1 │ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
   ·                         ────┬───
   ·                             ╰── End must be greater than or equal to Start
   ╰────
```
### After
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
true

# bytes at
❯  ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
true
```

fix range semantic in detect_columns, str substring, str index-of (#12894)
# Description
Fixes: https://github.com/nushell/nushell/issues/7761

It's still unsure if we want to change the `range semantic` itself, but
it's good to keep range semantic consistent between nushell commands.

# User-Facing Changes
### Before
```nushell
❯ "abc" | str substring 1..=2
b
```
### After
```nushell
❯ "abc" | str substring 1..=2
bc
```

Add string/binary type color to ByteStream (#12897)
# Description

This PR allows byte streams to optionally be colored as being
specifically binary or string data, which guarantees that they'll be
converted to `Binary` or `String` appropriately on `into_value()`,
making them compatible with `Type` guarantees. This makes them
significantly more broadly usable for command input and output.

There is still an `Unknown` type for byte streams coming from external
commands, which uses the same behavior as we previously did where it's a
string if it's UTF-8.

A small number of commands were updated to take advantage of this, just
to prove the point. I will be adding more after this merges.

# User-Facing Changes
- New types in `describe`: `string (stream)`, `binary (stream)`
- These commands now return a stream if their input was a stream:
  - `into binary`
  - `into string`
  - `bytes collect`
  - `str join`
  - `first` (binary)
  - `last` (binary)
  - `take` (binary)
  - `skip` (binary)
- Streams that are explicitly binary colored will print as a streaming
hexdump
  - example:
    ```nushell
    1.. | each { into binary } | bytes collect
    ```

# Tests + Formatting
I've added some tests to cover it at a basic level, and it doesn't break
anything existing, but I do think more would be nice. Some of those will
come when I modify more commands to stream.

# After Submitting
There are a few things I'm not quite satisfied with:

- **String trimming behavior.** We automatically trim newlines from
streams from external commands, but I don't think we should do this with
internal commands. If I call a command that happens to turn my string
into a stream, I don't want the newline to suddenly disappear. I changed
this to specifically do it only on `Child` and `File`, but I don't know
if this is quite right, and maybe we should bring back the old flag for
`trim_end_newline`
- **Known binary always resulting in a hexdump.** It would be nice to
have a `print --raw`, so that we can put binary data on stdout
explicitly if we want to. This PR doesn't change how external commands
work though - they still dump straight to stdout.

Otherwise, here's the normal checklist:

- [ ] release notes
- [ ] docs update for plugin protocol changes (added `type` field)

Avoid taking unnecessary ownership of intermediates (#12740)
# Description

Judiciously try to avoid allocations/clone by changing the signature of
functions

- **Don't pass str by value unnecessarily if only read**
- **Don't require a vec in `Sandbox::with_files`**
- **Remove unnecessary string clone**
- **Fixup unnecessary borrow**
- **Use `&str` in shape color instead**
- **Vec -> Slice**
- **Elide string clone**
- **Elide `Path` clone**
- **Take &str to elide clone in tests**

use to_lowercase in str downcase (#10850)
# Description
as we can see in the [documentation of
`str.to_lowercase`](https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase),
not only ASCII symbols have lower and upper variants.

- `str upcase` uses the correct method to convert the string

7ac5a01e2f/crates/nu-command/src/strings/str_/case/upcase.rs (L93)
- `str downcase` incorrectly converts only ASCII characters

7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124)

this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in
`str downcase`.

# User-Facing Changes
- upcase still works fine
```nushell
~ l> "ὀδυσσεύς" | str upcase
ὈΔΥΣΣΕΎΣ
```
- downcase now works

👉 before
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὈΔΥΣΣΕΎΣ
```
👉 after
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὀδυσσεύς
```

Update internal use of decimal to float (#10333)
# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320

Now make the internal codebase consistent in referring to this data type
as `float`.

Work for #10332

# User-Facing Changes

`decimal` has been removed as a type name/symbol. 

Instead of 
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use 
```nushell
def foo [bar: float] float -> float {}
```

Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`

# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`
- Update comment in script

Rename into decimal to into float (#9979)

# User-Facing Changes
`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

Clean up tests containing unnecessary cwd: tokens (#9692)
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).

move 'str substring' to only use ranges (#8660)
# Description

This removes all the old style of quasi-ranges before we had full range
support from `str substring`. Functionality should otherwise work, but
only with the official range syntax.

Removes the array and string forms of ranges from `str substring`.
Leaves only the official range support for range values.

Require that values that look like numbers parse as numberlike (#8635)
# Description

Require that any value that looks like it might be a number (starts with
a digit, or a '-' + digit, or a '+' + digits, or a special form float
like `-inf`, `inf`, or `NaN`) must now be treated as a number-like
value. Number-like syntax can only parse into number-like values.
Number-like values include: durations, ints, floats, ranges, filesizes,
binary data, etc.

Remove math eval command (#7284)
Reasoning: 

Most missing math commands are implemented with #7258.
The `meval` crate itself declares that it doesn't strive to stringent
standards (https://docs.rs/meval/latest/meval/#related-projects).
For example no particular special casing or transformations are
performed to ensure numerical stability. It uses the same rust `std`
library functions we use or have access to (and `f64`).
While the command call syntax in nushell may be a bit more verbose,
having a single source of truth and common commands is beneficial.
Furthermore the `math` commands can themselves implement broadcasting
over lists (or table columns).

Closes #7073

Removed dependencies:
- `meval`
- `nom 1.2.4` (duplicate)

User-Facing Changes:

Scripts using `math eval` will break. 
We remove a further `eval` like behavior to get results through runtime evaluation (albeit limited in scope)

Tests:

- Updated tests that internally used `math eval`.
- Removed one test that primarily used `math eval` to obtain a result from `str join`

Add decimals to int when using into string --decimals (#6085)
* Add decimals to int when using `into string --decimals`

* Add tests for `into string` when converting int with `--decimals`

* Apply formatting

* Merge `into_str` test files

* Comment out unused code and add TODOs

* Use decimal separator depending on system locale

* Add test helper to run closure in different locale

* Add tests for int-to-string conversion using different locales

* Add utils function to get system locale

* Add panic message when locking mutex fails

* Catch and resume panic later to prevent Mutex poisoning when test fails

* Move test to `nu-test-support` to keep `nu-utils` free of `nu-*` dependencies

See https://github.com/nushell/nushell/pull/6085#issuecomment-1193131694

* Rename test support fn `with_fake_locale` to `with_locale_override`

* Move `get_system_locale()` to `locale` module

* Allow overriding locale with special env variable (when not in release)

* Use special env var to override locale during testing

* Allow callback to return a value in `with_locale_override()`

* Allow multiple options in `nu!` macro

* Allow to set locale as `nu!` macro option

* Use new `locale` option of `nu!` macro instead of `with_locale_override`

Using the `locale` options does not lock the `LOCALE_OVERRIDE_MUTEX`
mutex in `nu-test-support::locale_override` but instead calls the `nu`
command directly with the `NU_LOCALE_OVERRIDE` environment variable.
This allows for parallel test excecution.

* Fix: Add option identifier for `cwd` in usage of `nu!` macro

* Rely on `Display` trait for formatting `nu!` macro command

- Removed the `DisplayPath` trait
- Implement `Display` for `AbsolutePath`, `RelativePath` and
  `AbsoluteFile`

* Default to locale `en_US.UTF-8` for tests when using `nu!` macro

* Add doc comment to `nu!` macro

* Format code using `cargo fmt --all`

* Pass function directly instead of wrapping the call in a closure

* Pass function to `or_else()` instead of calling it inside `or()`
