moved from reading String to reading bytes. A little faster, still need to implement for multithreaded solution

Actually I just needed to add target-cpu=native to [build] in Cargo.toml, did that and create HashMap with capacity, also added reference implementation (which uses libraries unlike my solution)

The polars solution I saw on reddit a few months ago is also super slow. I'm thinking it might be my macbook

Multi threaded works now but it's slower than single threaded...

Still broken but it compiles. For some reason lines are not properly being read and only one thread is being run

use hashbrown instead of std hashmap, no performance improvements
