WASM Artifact Image Specification should extend to support more layers #283

Is your feature request related to a problem? Please describe. We want to store plugin's metadata in the wasm OCI image, But the config layer is only for wasm runtime's configuration. image I think this spec should support extending more layers, for example, it can also support storing the plugin's README.md through a specific layer.

Describe the solution you'd like Indicate in the spec that there can be more than 2 layers, or add a layer to store plugin's arbitrary metadata.
