OCI Layout commands

What would you like to be added?

Interactive with an OCI layout

For the moment only copy to OCI layout is implemented

public void copy(ContainerRef containerRef, Path folder) {

Introduce a first level OciLayoutRegistry similar to Registry

Probably no need to implement all operation as a first step but perhaps

• Push artifact to OCI layout (oras push --oci-layout my-layout:foo hello.txt)
• Pull artifact from OCI layout (oras pull --oci-layout my-layout:foo --output tata)
• Pull manifest from OCI layout (oras manifest fetch --oci-layout my-layout:latest)
• Push manifest to OCI layout (oras manifest push --oci-layout my-layout:toto manifest)

Why is this needed for ORAS?
