Add module 30601 for bcrypt-sha256 v2
Module implements hashing according to version 2 of passlib's bcrypt-sha256. Code is based on modules 30600, 3200, and 28300. Version 1 of the hash could also be added to this, but the format of the generated hashes differs significantly in length, because of the increased verbosity of the new format. Example hash: $bcrypt-sha256$v=2,t=2b,r=12$n79VH.0Q2TMWmt3Oqt9uku$Kq4Noyk3094Y2QlB8NdRT8SvGiI4ft2 Reference: https://passlib.readthedocs.io/en/stable/lib/passlib.hash.bcrypt_sha256.html
