Adding the ability to decompose an input image "name" that
includes a digest. For example:
docker.io/library/fedora@sha256:64a02df6aac27d1200c2572fe4b9949f1970d05f74d367ce4af994ba5dc3669e
Also, reword the decompose method in a Decompose class. This simplifies the use of
decomposition and allows for growth.
Example usage:
registry, repo, image, tag, digest = Decompose("docker.io/library/busybox:latest").all
repo = Decompose("docker.io/library/busybox:latest").repo
digest = Decompose("docker.io/fedora@sha256:64a02df6aac27d1200c2...67ce4af994ba5dc3669e").digest
