Should we use `python-Levenshtein`?

[lukasugar]

Running the run_eval.py script outputs these warnings:

readbench/.venv/lib/python3.12/site-packages/fuzzywuzzy/fuzz.py:11: UserWarning: Using slow pure-python SequenceMatcher. Install python-Levenshtein to remove this warning

I'd like to run the evals as you've done it in the original research. Is that without [python-Levenshtein](https://github.com/ztane/python-Levenshtein/) or was it accidentally omitted from the requirements.txt? There can be some differences to the scores if the extra package is installed.

Thanks!
