hashx: Rust reimplementation of tevador’s HashX ASIC-resistant hash function

This is an ASIC-resistant hash function designed by tevador as a lightweight variant of RandomX’s SuperscalarHash, optimized for Tor’s client puzzle use case. Check out tevador’s dev log for more information.

This is for Tor client puzzle support in Arti. (#889)
