Adds some additional advance checks that Argon2 parameters are within range, and returns errors in the event they are not. This prevents a panic caused by what was previously an `unimplemented!` call when converting error types. The occurrence of the panic in the first place speaks to overall deficienciesin the `password-hash` crate's error handling strategy. It's further complicated by the awkwardness of the `password_hash::Output::init_with` API. The code in this commit has TODOs for addressing the above, but it'd be good to open issues upstream on the `password-hash` crate about these problems, and ideally update the TODOs in the code with references to the issues.

@izik1 unfortunately this doesn't give a good error for incorrect salt lengths (it's presently I'll open some issues about improving the error handling story in |

Now that error handling has been improved in `password-hash` v0.2, these are no longer needed as the errors will be properly handled in the `hash_password_into` function.
