Add hardware-accelerated implementation of SHA256 #36

Open zah opened 4 years ago

zah commented 4 years ago

Most modern CPUs offer specialized instructions for computing the SHA family of functions. For optimal power usage and maximum throughput in SSZ merkleization, we can benefit from such a hardware-accelerated implementation in Nimcrypto.
