kpod save can now save images to directories using the dir transport. Manifest conversion is also possible. To save with the oci manifest type set --format to oci-dir and to save with the v2s2(docker) manifest type, set --format to docker-dir. The layers can be compressed as well when saving to a directory using the --compress flag. Added functionality to kpod load to be able to load image from a directory Signed-off-by: umohnani8 <umohnani@redhat.com> Closes: #137 Approved by: rhatdan
