v0.0.12 Faaaast push/pull

This release contains BREAKING changes to the puller/pusher in support of a more efficient on-disk format in bazelbuild/rules_docker.

The new puller takes a --directory argument and emits the constituent elements as files under this directory as described in save.fast.

The new pusher is backwards-compatible, but the --tarball argument is used only for accepting a legacy base image on which the new intermediate format builds. The new layers and their digests are passed through repeated --layer and --digest arguments, in the order in which they should appear in the image's manifest. The v2.2 config file for the new image is passed via --config.

v0.0.11 Stamping

This adds support for Bazel stamping to the docker_pusher tool.

v0.0.10 Fix credential helper support

This fixes the credential helper handshake when the helper is asked about a registry domain for which it has no credentials.

v0.0.9 Fix local registry support

This fixes a final issue due to a bad assumption about the "empty layer"s availability when converting images between formats.
