Use packaging library to avoid DeprecationWarning from distutils (#435)

* Use packaging library to avoid DeprecationWarning from distutils

`distutils.version.LooseVersion` has been deprecated since
pypa/distutils#75.

This instead replaces that with `packaging.version.Version` from the packaging
library: https://packaging.pypa.io/en/latest/.

* Bump Black version to include fix for new Click release with breaking changes

Click 8.1.0 was recently released which removed deprecated features. Black used
to depend on the deprecated features, but that was fixed in version 22.3.0 so
it again works with the latest version of Click.

* Update AUTHORS and CHANGELOG
