The `Salt` and `SaltString` types are wrappers for B64-encoded salt strings as used by the PHC string format. These API changes make it clearer that the input string needs to be B64-encoded. The old API is preserved but with deprecations to ease upgrades. The following methods were renamed: - `Salt::new` => `Salt::from_b64` - `Salt::b64_decode` => `Salt::decode_b64` (for consistency) - `SaltString::new` => `SaltString::from_b64` - `SaltString::b64_decode` => `SaltString::decode_b64` - `SaltString::b64_encode` => `SaltString::encode_b64` The `Salt::as_bytes` and `SaltString::as_bytes` methods were removed, as they return the B64-encoded string as bytes, rather than decoding B64 to bytes, which is what a user might be expecting.
