Bunch of improvments

[MaxGraey]

• speedup blake2b64 (I hope so, didn't really benchmarking)
• update AssemblyScript to 14.0.0
• other improvments and refactorings

Wow, thank you so much! This is really amazing.

I didn't expect there to be so much improvement in speed left without making it unreadable, but you've done a really good job. I am super impressed because the code you optimized wasn't the most clear anymore after I iterated on it a lot for speed (sorry about that!).

My poor man's benchmark has been to edit the expectation here and make it really high (e.g. 10 million). And then run:

npm run test:as -- --file solver.astest.ts

This runs in Node, I've found that it's up to in Chrome or Firefox it can be another 50% faster (my node version is 12.13.1).

Without your changes (3 runs):

[Actual]: 3952569.169960474

We went from 2.25 million hashes to 4 million hashes per second, really impressive! I didn't expect this to be possible without SIMD. The build size went from 3.44KB to 3.24KB, so even there it's a small improvement 🚀.

What do you think btw made external assemblyscript module for blake2b64 (as-blake2b)? Similar to as-sha256

[gzuidhof]

Yeah I'd be happy to make it an external module, but we do need to verify that the implementation is actually correct.

All my tests and use cases are passing in a single message that is under 128 bytes, who knows whether it is also correct for longer messages, and messages that are streamed.

Feel free to merge when you are ready! thanks again

Oh, definitely need more tests)

It's ready
