Add Tournesol to alternatives Youtube clients

[roipoussiere]

There are several open-source Youtube clients:

• Invidious (web app) (source);
• FreeTube (desktop app) (source);
• NewPipe (mobile app (source);
• SkyTube (mobile app) (source);

These are front-end alternatives that allow users to watch Youtube videos without sending too much information to Google with interesting features like the ability to follow channels without a Google account.

Since these client have a full control on the UI, they have full control on how to recommend videos to users. Therefore it makes sense here to use an alternative to the Youtube recommendation system, such as Tournesol.

Their users are probably concerned about Youtube supremacy so it could be an efficient way to offer Tournesol to people that want it, and to promote the project. Their developers may accept to add such a feature in their code base if it's well integrated on the UI.

So I wonder if the Tournesol organization and community would want to give some resources and time to contribute to these projects this way.

Edit: having a good recommendation API that allows developers to easily retrieve recommendations and use them in their project (that can be an alternative Youtube client or something else) is probably a good approach.
