 * Downloads an OCI Artifact from a remote OCI Registry and writes it to the disk.
 * The artifact here is a custom rules bundle stored in a remote registry.
 * In order to do that, it calls an external docker registry v2 client to get the manifests, the layers and then builds the artifact.
 * Example: https://github.com/opencontainers/image-spec/blob/main/manifest.md#example-image-manifest
 * @param OCIRegistryURL - the URL where the custom rules bundle is stored
 * @param opt????? (optional) - object that holds the credentials and other metadata required for the registry-v2-client
