json, yaml, toml, xml, html, csv are now normal formats and most of them also particiate
in probing (not html and csv).
Also fixes a bunch of bugs in to/fromxml, to/fromjq etc.
Add toxml/fromxml for XML encoding, mighe be lossy on ordering
fromxml has {seq:bool} to add #seq attributes to improve ordering
toxml has {indent:number} to choose space indent depth
Add tojson, same as in jq but also has {indent:number} options
Add toyaml/fromyaml for YAML
Add totoml/fromtoml for TOML
Add tojq/fromjq for jq-flavored JSON (optional quotes for keys, comments and trailing commas support)
Add tocsv/fromcsv for CSV
formcvs takes {comma:string, comment:string} for custom separtor and comment character
Rename/split hex into tohex/fromhex
Rename/split base64 into tobase64/frombase64
tobase64/frombase64 takes {encoding:string} option for base64 flavour (std, url, rawstd, rawurl)
Add to/from<format> urlpath, urlquery, url, xmlentities, base64, hex
Add to<hash> md4, md5, sha1, sha256, sha512, sha3_224, sha3_256, sha3_384, sha3_512
Add to/from<encoding> iso8859-1, utf8, utf16, utf16le, utf16be
Add explode for binary that explode into an array of the binary unit tobits
Remove scan_toend as it feels a bit weird and one can use tobytes | .[match(...):] instead
Some general cleanup also
Now repl, slurp and help implemented using same query rewrite.
Include filename context in error if possible.
Add spew function that does opposite of slurp.
Start of help infra, not done or documented yet.
Show error pointer on parse error.
Rename internal eval to _eval and make eval be wrapper that
does rewrite and has various eror handling etc.
Nicer repl, slupr and help errors.
Rename buffer to binary. Still some work left what to call buffer/binary in decode code.
Document decode value and binary type
Fix proper unit padding for tobytes and add still undocumenated extra padding argument.
Add some additional binary tests
Now all regexp functions should work similar to string version for buffers.
Added scan_toend that works as scan but outputs buffer from match to end of buffer,
useful when trying to decode a format and you dont know or care to limit.
