Add automated Docker image builds

* Removed redundant `setup.py` file. `pip install`, for example, will
  prefer the pyproject.toml file, and we didn't notice that file exists,
  so we were confused for too long about why our changes to `setup.py`
  were not "registering".
* Add pdgstaging dependency to `pyproject.toml`
