/// Generates a storable server email hash from a client hashed email.
///
/// Takes in a client hashed email, outputs a storable new hash. The returned result is 'safe' to
/// be stored on the server side database. The salt returned is for the hashed version of the
/// hashed client email.
///
/// Arguments:
/// hashed_email - The client hashed email sent to the server.
///
/// Returns: a tuple containing the final hash and the hash's salt, nothing on failure.
///
/// Example:
/// ```rust
///     let enc = hash_email("THISISTOTALLYAHASHEDTHING...").unwrap();
///     println!("Server Email Hash: {}", HEXUPPER.encode(&enc.0));
///     println!("Server Email Salt: {}", HEXUPPER.encode(&enc.1));
/// ```
