- Added experimental support for Google Consent Management. Add the `f3cc/gcm.js` asset to pass the users general consent to GA.

utility; you could e.gg. use `import micawber; providers = micawber.bootstrap_oembed(); embed(..., oembed_json=providers.request)` now.

nothing to add inside.

"privacy policy" title at the end.

`<div class="responsive-embed">` element when using `oembed`.

`f3cc.js` because it's nicer.

- Updated pre-commit hooks.
- Added Django 4.2a1 and Python 3.11 to the CI.
- Django 5.0 will require Python 3.10 or better, updated the CI to take this
into account.
- Documented a better way to integrate the inject view. (Still only really
useful for special cases.)
- Code golfed the generated JavaScript a bit to shave off a few bytes.
- Added a `oembed` embedder to `feincms3_cookiecontrol.embedding`.

- Added the `--f3cc-accept-foreground` CSS variable.
