FxHashMap made me faster, memmap makes me slower, guess I'm using it wrong

add solution using libraries to see how fast I can get. For now no difference

some improvements by reducing the casts, implemented a get_pos function to get position of byte in byteslice by bitmasking... slightly slower

use read_until method instead of custom function because it is faster than mine using the Bytes struct

My multi-treaded version is now faster than polars and takes less time to compile. It's a little more complex though

managed to make my solution super fast... but it's also incorrect

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
