This PR closes #701 and closes #710.

• Update version number.
• Update conda recipe. Make it a noarch recipe again based on the conda-forge recipe. Remove conda_build_config.yaml since we don’t need it anymore. Also update the conda-recipe README.
• Drop Python 3.7 from the README and from setup.py.
• Use Python 3.8 for ReadTheDocs builds as well.

The conda package has been uploaded to the ets channel. The source tarball has also been uploaded to the test.pypi.org. See passing builds on Linux and Windows for both packages below.
