Notes

The C version of fzy in that repo contains 2 differences with the original:

• the functions take a is_case_sensitive additional parameters that does what you think. It's a parameter rather than computed in the function because for our use-case, you want to compute is_case_sensitive once for needle, instead of on each iteration of the loop.
• match_positions uses uint32_t for positions, because size_t (uint64_t) doesn't map well to lua types.
