Build GitHub actions based CI to publish to PyPI on releases

[whatnick]

I would like to contribute by building a GitHub actions based CI to publish to PyPI on release tags. As a pre-requisite for this to ensure code quality and stability an appropriate PyCQA suite and Testing suite is necessary.

Sounds great. I'll need to revise my general development and QA processes to match with the automation (A good thing).

For reference (https://github.com/VUnit/vunit/blob/master/.github/workflows/push.yml#L193-L227):

  deploy:
    runs-on: ubuntu-latest
    if: github.event_name == 'push' && startsWith(github.ref, 'refs/tags/v')
    steps:

    - name: '🧰 Checkout'
      uses: actions/checkout@v2
      with:
        submodules: recursive

    - name: '🐍 Setup Python'
      uses: actions/setup-python@v2
      with:
        python-version: 3.9

    - name: '🐍 Install dependencies'
      run: |
        pip install -U pip
        pip install -U setuptools wheel twine
        
    - name: '🚀 Build and deploy to PyPI'
      if: github.repository == 'j0ono0/pinout'
      env:
        TWINE_USERNAME: __token__
