Derek McGowan 1fd2d66df8 Fix manifest lists to always use correct size
Stores complete OCI descriptor instead of digest and platform
fields. This includes the size which was getting lost by not
storing the original manifest bytes.

Attempt to support existing cached files, if not output
the filename with the incorrect content.
