Add type hints to all defs and enable `disallow_untyped_defs` #162

	name: Run unit tests with oldest dependency versions
	# This workflow runs the unit tests with the oldest versions of the
	# dependencies listed in `pyproject.toml`. The oldest versions are specified in
	# `ci/minimum/requirements.txt`. The `requirements.txt` file is needs to
	# be manually updated to be aligned with `pyproject.toml`.
	#
	# In the future, `pip` might be able to install the minimum versions in
	# `pyproject.toml` directly as disscussed in an open issue:
	# https://github.com/pypa/pip/issues/8085
