Andreas Auernhammer 625c6a7b44 argon2: add new package implementing the Argon2 PBKDF family 
This CL adds the package argon2. The argon2 package implements
the Argon2 PBKDF family (Argon2i, Argon2d, Argon2id).

Argon2 is memory-hard key derivation function and is specified
at https://github.com/P-H-C/phc-winner-argon2/blob/master/argon2-specs.pdf
It can be used to derive cryptographic keys with high entropy from low
entropy passwords.

Fixes golang/go#19896
