chore: add tooling

- `.editorconfig`: [EditorConfig](http://editorconfig.org/) maintains consistent coding styles between different editors and IDEs
- `.gitignore`: generated python and macos common exclusions while retaining existing exclusions
- `.tool-versions`: [asdf](https://asdf-vm.com/) version manager configuration for python and [poetry](https://python-poetry.org/) dependency manager
- `demo.py`: rename from `demoEx2.py` to `demo.py` to match documentation; added interpreter; made executable
- `pyproject.toml` and `poetry.lock`: poetry configuration\
- `requirements.txt`: generic python requirements file suitable for backwards compatibility with other python dependency managers and vesions listed in `setup.py`
