Use quick-score

Uses the quick-score library for fuzzy searching, replacing fuse.js. A quick-score demo can be found here. In my opinion this scoring algorithms performs better on our set of categories and I also haven't noticed any weird things happening (yet).

(quick-score doesn't have typescript types - I defined the types for the parts of the library we need in search.d.ts)

I would be critical merging this, but the alternative would be to revert the fuzzy search MR
