CheckHash is like ComparePasswordAndHash, except it also returns the params that the hash was created with.

ComparePasswordAndHash performs a constant-time comparison between a plain-text password and Argon2id hash, using the parameters and salt contained in the hash.

CreateHash returns a Argon2id hash of a plain-text password using the provided algorithm parameters.

DecodeHash expects a hash created from this package, and parses it to return the params used to create it, as well as the salt and key (password hash).
