Try with codespell instead

Codespell does not check against a dictionary, so niche terms don't trigger false-positives. Could actually alleviate the need for skip/ignore option.

I think codespell could be used as an option, such as a "strictness" level

For example strict=low would use codespell, while strict=high would use dictionaries. I personally prefer the dictionary-based implementation.

I see, thanks for your feedback :)
I do think it would be nice to have multiple spellcheck backends that users can enable/disable at wish.
