Optimize SALT

[jesperpedersen]

Optimize the SALT implementation, and see how it affects iteration count.

Hmm /src/common/hmac.c isnt in this repo, nor is scram_SaltedPassword. only scram_sha256 exists here

[jesperpedersen]

@n0rbed You have to learn our implementation in mainly security.c. The email thread is just for the general idea, none of its source code will apply to pgagroal's code base

Take a look at https://datatracker.ietf.org/doc/html/rfc7677 and friends
