Licensing concerns

[zerogerc]

Hi, thanks for the awesome library.

Is there any way to remove python-Levenshtein from the dependencies? It's licensed under GPLv2 which is not compatible with MIT of errant.

This wasn't something I was aware of - thanks for letting me know!

I'll look into using an alternative, but in the meantime, you can try python's difflib.SequenceMatcher which is what ERRANT v2.1.0 relied on before python-Levenshtein.

Thanks a lot, I'll take look.

I should probably add that difflib.SequenceMatcher was ~3x slower than python-Levenshtein (which is why I changed it in the first place) so don't be surprised if you take a performance hit. At least it gets around the licensing issue though.

As a follow-up, I also found out that the RapidFuzz package should be a good alternative (MIT license), which should also be faster than python-Levenshtein so I'll look at officially adding that at some point!

[chrisjbryant]

Just pushed ERRANT v2.3.1 which now uses RapidFuzz instead of python-Levenshtein so the licensing conflict is resolved!

Great news. Thanks a lot for the help!
