Collectfast: A Faster Collectstatic for Django

Collectfast dramatically speeds up Django's `collectstatic` command when using cloud storage by only uploading static files that have changed. It leverages MD5 hashes (ETags) or modification times to determine if a file needs to be re-uploaded. The current version is 2.2.0, with a release cadence of a few times per year, focusing on compatibility and performance improvements.
