This change adds granular, non-docker daemon docker image fetchers and a docker image layer compositor to be used in conjunction with the `docker2nix` utility provided by the `haskellPackages.hocker` package. This change includes a hackage package version bump and updated sha256 for recent fixes released to `hocker` resulting from formulating this patch.

# because the paths are absolute and docker load wants them flattened in
|
|
# the archive, we need to transform all of the paths going in by
|
|
# stripping everything *including* the last solidus so that we end up

# with the basename of the path.
