  * cyrb53 hash for string from: https://stackoverflow.com/a/52171480

  * It is roughly similar to the well-known MurmurHash/xxHash algorithms. It uses a combination
  * of multiplication and Xorshift to generate the hash, but not as thorough. As a result it's
  * faster than either would be in JavaScript and significantly simpler to implement. Keep in
  * mind this is not a secure algorithm, if privacy/security is a concern, this is not for you.
