Remaining task list

[a-reich]

• packaging: migrate package configuration from setup.py to declarative setup.cfg (or eventually pyproject.toml when setuptools supports it). Can delete setup.py or keep a shim around for compat with older setuptools Done, can remove the empty cfg when setuptools supports PEP 660 editable installs.

• add support for other params of pickle interface (eg protocol)

• Code quality: lint with flake8. Add mypy, flake8 to CI.

• add an interface for customizing validation logic (eg through a callback or subclass) ?

• Add doc build to CI?
