Native Go implementation of HighwayHash (library)

 This library is a native Go version of HighwayHash with optimized assembly
 implementations on Intel and ARM, Able to process over 10 GB/sec on a single
 core on Intel CPUs.
 .
 HighwayHash is a pseudo-random function (PRF) developed by Jyrki Alakuijala,
 Bill Cox and Jan Wassenberg (Google research). HighwayHash takes a 256 bit key
 and computes 64, 128 or 256 bit hash values of given messages.
 .
 It can be used to prevent hash-flooding attacks or authenticate short-lived
 messages. Additionally it can be used as a fingerprinting
 function. HighwayHash is not a general purpose cryptographic hash
 function (such as Blake2b, SHA-3 or SHA-2) and should not be used if
 strong collision resistance is required.
