argon2: add Argon2id and update parameter recommendations

This change exports the Argon2 variant Argon2id and improves documenation.
The following parameter recommendations are added:
 - Argon2i:
   time=3 and max. memory for non-interactive scenarios as recommended by the
   RFC draft https://tools.ietf.org/html/draft-irtf-cfrg-argon2-03#section-9.3
 - Argon2id:
   time=2 and memory=64MB for interactive scenarios as used by libsodium >= 1.0.9
   https://download.libsodium.org/doc/password_hashing/the_argon2i_function.html

   time=1 and max. memory for non-interactive scenarios as recommended by the
   RFC draft linked above.

Fixes golang/go#23602
