Add Klaro! (and COOKiES?) support

Indeed that will be needed.

COOKiES has higher priority here, but since COOKiES is mainly client side, we need to find a way on how to solve this when setting cookies via the server.

Many alternative storage methods are now present in ✨ Add option to use other storage methods Active so I think this won't be needed. Otherwise happy to review a MR if anyone wants to.
