This PR adds OCI Image Spec v1.1 artifact support. It extends Manifest, Index, and Descriptor with the `subject` and `artifactType` fields, adds a `referrers()` method to RegistryClient implementing the OCI Distribution Spec v1.1 referrers API. Also, I've added some unit unit tests for backward compatibility and roundtrip encpding of all new fields
