fast, fully fledged murmur3 in Go

 This package contains a native Go implementation of Austin Appleby's
 third MurmurHash revision (aka MurmurHash3).
 .
 The reference algorithm has been slightly hacked as to support
 the streaming mode required by Go's standard Hash interface
 .
 Unlike the canonical source, this library always reads bytes as little
 endian numbers.
 This makes the hashes portable across architectures, although does mean
 that hashing is a bit slower on big endian architectures.
