### Expected behavior

Can you please add support for Jinx spell checker? https://github.com/minad/jinx

Main feature for me is performance. If you use spell-fu with Italian(or others) dictionary you get this issue: https://codeberg.org/ideasman42/emacs-spell-fu/issues/40

### Current behavior

spell-fu is slow and uses lots of memory with some dictionaries.

### Steps to reproduce

1. Install aspell-it dictionary (if using aspell)
2. Enable spell-fu / aspell
3. Open Emacs
4. re-create spell-fu cache
5. This will take 5 minutes
