Windows port

[BenjaminDev]

Description

Working on #112. This is new PR on the same issue as a number of the initial changes have been correctly moved upstream see google/differential-privacy#47 (still open) and google/differential-privacy#34 (closed)

Adding windows support for PyDP.

Notes

There are 4 files changed here but only 2 are needed when the upstream library merges PR google/differential-privacy#47

Required changes to python-dp to support windows:

1. Added workflow done here
2. Added _pydp.pyd to setup.py package_data={"pydp": ["_pydp.so","_pydp.pyd"],}, so the windows package includes the built binary.

Extra changes that are WIP for now and will be reomved when PR google/differential-privacy#47 is merged.

3. Updated .gitsubmodules to point to my personal fork of the google/differential-privacy
4. Moved the SHA that we build against to after the upstream library merged google/differential-privacy#34

   Windows python-dp wheels

   If you want to test the wheels or use for a demo feel free to look here for a windows wheel:

   python -m venv .venv
   .\venv\Scripts\activate
   (.venv)$ python -m pip install https://github.com/BenjaminDev/PyDP/releases/download/3.8-0.1.7-win_amd64-beta.7/python_dp-0.1.7-cp38-cp38-win_amd64.whl
   (.venv)$ python -c "import pydp; print(pydp.__version__)" 

Affected Dependencies

Moved base library to a private fork. Don't merge yet WIP. See notes above.

How has this been tested?

• Ran pytest tests against the built wheels for all python versions and they all passed see

Update:

• The upstream PR was accepted and merged! Thanks @dasmdasm
• Added CI tests for macOS and windows.
• Added twine check dist/* as we now reading in a .rst for long_description in the setup.py file.

Notes: To support windows I had to add configs to the .bazelrc file and so when you build you'll need to add --config Linux, --config macOS or --config Windows. I have not updated the make files nor scripts with this change. It's a easy fix if you run into it and a small change to fix. I just cannot test make and .sh files on this windows box. So to build on linux bazel build --config Linux .......
