Add fuzzy search to text searching in text spotting code

[rwood-97]

Is your feature request related to a problem? Please describe.
Relates to #502 in which I have added the search_preds method.
At the moment, this accepts regex but doesn't do fuzzy string matching.

We would like to allow users to use fuzzy matching as an option when searching preds.
This can be done with thefuzz library.

Won't be finished before March 31st but will upload all code I have in this ticket/create a draft PR
