Read thumbnail and title from data-attribute for contextual consent

Ic created a Merge request. Beside the code I have added example code to the README.md

What do you think, should we add the data attributes by ourselves (by option) for Media Remote Video or just provide the sample code?

This looks amazing and is a great new feature.

WRT preprocessing, could that be made a little more generic? I.e. checking if the media entity has a thumbnail entity. That way, we wouldn't have to hard-code the bundle name remote_video as that name could be different on other installations.

I have made the code and the example a bit more general. But we should avoid exposing fields if they are not needed. More field preprocessors can be proposed as a feature request.

This looks nice now, thank you.

Thank you. I merged the MR (with small corrections).
