Add support for dir transport to kpod save

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
