Highlights: more 2 way parallel implementations, AES for shavite.
Remioved some obsolete code that should make it easier to suport ARM.
AES is working in general and enabled for Shavite & Echo. Groestl and Fugue still
have their own issues.
Upgraded development environment:
* Orange Pi 5 Plus 16 GB, Rockchip 8 core CPU with AES & SHA2
