Update requirements and metadata (#47)

* Update requirements and metadata

typing: python <3.8 (due to still not completed)
setup_requires & python_requires in setup.py due to old setuptools logic
project_urls for packaging

* Move URLs to setup.cfg

This attributes are parsed by modern setuptools only, so reduce warnings
