Subject: [PATCH] Add pre-commit configuration and integration for
 REUSE.software.

pre-commit.com provides a way to configure pre-commit hooks for multiple
tools, including `reuse lint` (configured here), isort, black, and more.

This is also integrated with GitHub actions in the example configuration.
