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

Colleagues asked for decompose to be improved to where it took
an image name and broke it into registry, repo, image, and tag.
It also should mimic docker's implementation where 'library' is a known
exception
Also added unittests for decompose. Removed a singular glob test
as it is no longer valid

Enabling signing and pushing at the same time. At the time of
this writing, we cannot verify that the atomic targets are
working but the code is there. THis is enabled with the
--type atomic switch. Otherwise, signatures are written locally
and the image is pushed.
