Compress the languages data

[apocelipes]

There is a lot of repeated content in languages.json, so using gzip compression can
significantly reduce the size of both the generated Go file and the compiled binary file.
A small binary file can use less momory and have a better cache hit rate.

On my windows machine with go1.22, it shows:

• "processor/constants.go": 170k -> 20k, 150k reduced.
• scc binary file: 8909k -> 8836.5k, 72.5k reduced.

Gzip is very fast, as hyperfine reports there's nearly no harm on the performance:

$ cd scc
$ hyperfine --warmup 5 'scc.exe .' 'scc-nocompress.exe .'
Benchmark 1: scc.exe .
  Time (mean ± σ):      59.0 ms ±   2.6 ms    [User: 9.0 ms, System: 18.2 ms]
  Range (min … max):    55.6 ms …  65.3 ms    45 runs

Benchmark 2: scc-nocompress.exe .
  Time (mean ± σ):      59.2 ms ±   2.9 ms    [User: 8.8 ms, System: 17.8 ms]
  Range (min … max):    55.5 ms …  66.5 ms    46 runs

This is very interesting. Not the biggest saving, but having scc on a diet isnt a bad idea.

Going to merge but possibly revert if I notice any issues in the future or slowdown.
