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`.
