// Sum128 returns the murmur3 sum of data. It is equivalent to the following
// sequence (without the extra burden and the extra allocation):

// hasher := New128()
// hasher.Write(data)

// SeedSum128 returns the murmur3 sum of data with digests initialized to seed1
// and seed2.
//
// The canonical implementation allows only one uint32 seed; to imitate that
// behavior, use the same, uint32-max seed for seed1 and seed2.
//
// This reads and processes the data in chunks of little endian uint64s;
// thus, the returned hashes are portable across architectures.
