What works:
* Most algorithms are working with Neon optimizations, 2-way parallel when applicable.
* AES is working for Shavite and Echo.
* SHA is working for all algos.
* stratum+ssl and stratum+tcp are working, GBT is untested but expected to work.
* all configurations options work as usual.
Known problems: Known problems:
