fix(js): use pure JS SHA256 library, refactor (#471)
* fix(js): use pure JS SHA256 library, refactor Closes #458 Additionally, I made a horrifying discovery: Firefox seems to actively hinder performance if you are using more than one Worker per page. It does not spread the load out across cores like I expected. Instead it seems to make that one Worker thrash and have to constantly context switch, which caused a lot of slowdown. The benchmarks in #155 continue to be the best contribution ever made to Anubis. What clued me into there being a problem here was the fact that the "slow" algorithm was faster than the "fast" algorithm on my laptop. This made no intuitive sense to me so I dug further. Either way I think this is a Firefox bug at its core, but for now we have to work around it by doing the hacky terrible thing that I hate. I also swapped the SHA256 operations to @aws-crypto/sha256-js on the advice of a trusted cryptography expert. I don't know what performance differences this makes, but I'm getting 150-225 kilohashes per second, which is pretty dang good.
