Add automated pypi release support

[kunikachandra]

This PR will partially solve (the pypi part) issue #46. After this the selector package will be accessible via pypi pip.

1. The project owners will need to 'Add a new pending publisher' in pypi https://pypi.org/manage/account/publishing/ with the name selector or qc-selector (pyproject.toml line 26 needs to be changed to qc-selector if we want pip install qc-selector to work).
2. Create a new API token under https://pypi.org/manage/account/
3. In the GitHub settings create a new environment secret with the variable name PYPI_API_TOKEN and paste the API token.
4. Create a new release to trigger the package build and publish to pypi.

@FanwangM should I create a new PR for setup.py or commit in this PR only?

Also, should I change the name to qc-selector instead of selector for the pypi package because selector is already taken by a previous project?

You can keep adding new things into this PR. And we would prefer using the qc-selector. @kunikachandra Thanks for helping with this.
