argon2: Update `password-hash` to 0.6

[tyilo]

I'm using the argon2 crate with the password-hash feature. I have my salt stored as a byte array, but version 0.5.0 of password-hash seems to only allow creating a Salt from a base64-encoded string, but I would like to create a Salt directly from a byte array.

It seems like version 0.6 of password-hash fixes this by using phc::Salt which can be created from a byte slice.

Line 26 of the Cargo.toml for the argon2 project on master branch states:

password-hash = { version = "0.6", optional = true, features = ["phc"] }

The version of argon2 from crates.io still uses password-hash version 0.5. However, since password-hash version 0.6.0 itself is published there, if you get just argon2 directly from GitHub, you should be able to work with the newest versions of both without any further changes.

What worked for me was running:

cargo add --git https://github.com/RustCrypto/password-hashes argon2

Ah, then I'm just waiting for a new release of argon2. @tarcieri any idea if that will happen soon? 🙏
