This is a native Rust generic implementation of the `pseudo_encrypt` function [from Psql](https://wiki.postgresql.org/wiki/Pseudo_encrypt)
> pseudo_encrypt(int) can be used as a pseudo-random generator of unique values. It produces an integer output that is

There is out of the box support for integer primitives that are 32bit and up:
- i32
- u32
- i64
- u64
- i128
