Install using the setuptools.build_meta backend

Installing with `pip install -e .` fails due to setup.py being
deprecated after setuptools adopted PEP-517 [1]. Migrate to building
using a setup.cfg file.

This was mostly a 1-to-1 migration except for setting
`install_requires`. Setuptools recommends not reading `requirements.txt`
as the value for `install_requires` [4].
