Supports for joaat and others

[Roms1383]

In gaming development there's some commonly used non-cryptographic hashing algorithms like joaat, crc32, fnv-1a (coming with 32 and 64bits variants) and I think it could be a nice addition to Crypto functions in SurrealDB.

It can be implemented very easily since crates out there already exists (e.g. joaat) and usually do not add up much to the size of the dependencies. In the worst case, they are usually pretty straightforward to re-implement by hand.

What do you guys think about it?
