Change Hunspell provider

[ZJaume]

cyhunspell is not only lacking binaries for version 2.0.3 but also now failing compilation for Python 3.12 (see mozilla/translations#983). chunspell seems that has solved the compilation issues and it is also distributing binaries, so probably changing cyhunspell by chunspell in the requirements just works.

A quick check that only changes the dependency seem that works. The tests are passing and a sample of Serbo-Croatian sentences is giving the same output. But for some reason, chunspell seems to be slower, 5.5s compared to 2.7s.

Done!

Reopening for some performance analysis...

• FastSpell 0.12 (cyhunspell) : Elapsed time: 36.62
• FastSpell - chunspell (ots) : Elapsed time: 90.57

Also, results are different:

diff fs-cyhunspell.txt  fs-chunspell.txt --side-by-side --suppress-common-lines  | wc -l
533
