This cleans up the API in general, removing a bunch of deprecated stuff,
cleaning up circular imports, etc.
But the biggest change is switching to an optional XML format for the
regex lexer.
Having lexers defined only in Go is not ideal for a couple of reasons.
Firstly, it impedes a significant portion of contributors who use Chroma
in Hugo, but don't know Go. Secondly, it bloats the binary size of any
project that imports Chroma.
Why XML? YAML is an abomination and JSON is not human editable. XML
also compresses very well (eg. Go template lexer XML compresses from
3239 bytes to 718).
Why a new syntax format? All major existing formats rely on the
Oniguruma regex engine, which is extremely complex and for which there
is no Go port.
Why not earlier? Prior to the existence of fs.FS this was not a viable
option.
Benchmarks:
$ hyperfine --warmup 3 \
'./chroma.master --version' \
'./chroma.xml-pre-opt --version' \
'./chroma.xml --version'
Benchmark 1: ./chroma.master --version
Time (mean ± σ): 5.3 ms ± 0.5 ms [User: 3.6 ms, System: 1.4 ms]
Range (min … max): 4.2 ms … 6.6 ms 233 runs

Time (mean ± σ): 50.6 ms ± 0.5 ms [User: 52.4 ms, System: 3.6 ms]

Time (mean ± σ): 6.9 ms ± 1.1 ms [User: 5.1 ms, System: 1.5 ms]

'./chroma.master --version' ran
1.30 ± 0.23 times faster than './chroma.xml --version'
9.56 ± 0.83 times faster than './chroma.xml-pre-opt --version'
A slight increase in init time, but I think this is okay given the
increase in flexibility.
And binary size difference:
$ du -h lexers.test*
$ du -sh chroma* 951371ms
8.8M chroma.master
7.8M chroma.xml
7.8M chroma.xml-pre-opt
