…ting to connect to a booting server (gmr#133)

- Change to use `ssl.SSLContext` since `ssl.wrap_socket` was deprecated
  in Python 3.7 and removed in 3.12
- Drops support for Python < 3.8
- Adds support for Python 3.10, 3.11 and 3.12

Change to use ssl.SSLContext

- Replace setup.cfg and setup.py with pyproject.toml
- Add dependencies to pyproject.toml

- Add `test` Github workflow that run tests and upload coverage to
  codecov. This expects a `CODECOV_TOKEN` secret token
- Add `deploy` Github workflow to build and publish tags to PyPI. This
  expects trusted published to be configured.

Addressed some misconfigurations in the Github Actions yaml
