Support Hashing Passwords
A fix I recently described to @dlrobertson on the dev-chat for an issue with API breakage causing this crate to break made me think of password hashes needing to be specified for configuration files for this program rather than just giving it a password to hash. I don't see any reason for not allowing the crate to hash passwords and serialize them using argon2rs
instead of requiring the password to be pre-hashed.
