use levenshtein distance (fuzzy search) for model names

[Efreak]

there's a library at taleinat/levenshtein-search that can be used for levenshtein searching.

An alternative is just filtering the list by the characters used, but for only a few characters this won't be useful, and won't help with putting most relevant results on top. (with levenshtein, sort by distance to get most relevant results on top)

reasoning: i keep typoing sdxl as sexl because my fingers are a bit off on my tablet (fun fact, touch typing hurts more than it helps on a mobile device). another common one is hitting the n key instead of the space key, and in termux i keep having to redo my cut buffer because i accidentally hit the wrong key :(
