encode/decode for multiple alphabets (#13428) 
Based on the discussion in #13419.


## Description

Reworks the `decode`/`encode` commands by adding/changing the following
bases:

- `base32`
- `base32hex`
- `hex`
- `new-base64`

The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.

All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.


## Example usage

```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```

```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000:   74 65 73 74                                          test
```


## User-Facing Changes

- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.

nu-cmd-extra

The commands in this crate are the extra commands of Nushell. These commands are not in a state to be guaranteed to be part of the 1.0 API; meaning that there is no guarantee longer term that these commands will be around into the future.

For a while we did exclude them behind the --features extra compile time flag, meaning that the default release did not contain them. As we (the Nushell team) shipped a full build including both extra and dataframe for some time, we chose to sunset the extra feature but keep the commands in this crate for now. In the future the commands may be moved to more topical crates or discarded into plugins.
