Decided to change hasher from std to AHash instead of fxhasher, no idea about perf, havent tested

Seems like there is some perf reduction on master, cant pin point what exactly is causing the perf degradation, but I am suspecting the use of Ahash is affecting it

Regarding this issue, I think we should just parameterize the hashmaps rather than using the different hasher

Using Fxhash is causing this problem
