instead of Python packages
As usual with Python sadness, the @pydeps wheels are built on the bazel
host, so stuffing them inside a container_image (or py_image) will cause
new and unexpected kinds of misery.

rules_pip has a new version [1] of their rule system, incompatible with the
version we used, that fixes a bunch of issues, notably:
- explicit tagging of repositories for PY2/PY3/PY23 support
- removal of dependency on host pip (in exchange for having to vendor
wheels)
- higher quality tooling for locking
We update to the newer version of pip_rules, rename the external
repository to pydeps and move requirements.txt, the lockfile and the
newly vendored wheels to third_party/, where they belong.
