To do so, have (skopeo copy) work with a types.Image, and replace uses of types.ImageSource with types.Image where possible to allow the caching in types.Image to work. This is a slight behavior change: - The manifest is now processed through fixManifestLayers - Duplicate layers (created e.g. when a non-filesystem-altering command is used in a Dockerfile) are only copied once.
