Add Piped as an option under "Preferred YouTube addon"

Feature suggestion

Detailed Description
The "Preferred Youtube addon" setting in Kore allows you to change between using the YouTube or the Invidious addon for YouTube videos, but there is a third addon that is great for watching YouTube videos: Piped Addon for Kodi.

Context

Piped is a great way to watch YouTube videos privately, something which matters to me greatly. I was attracted to Kodi specifically because it is open source and therefore more private, and I imagine I am very much not alone here. Piped is perfect for this, and it would be great if Kore could support it.

This was previously discussed on the Piped for Kodi GitHub, but the result of the discussion was that work would need to be done on Kore's end to support Piped. From what I gather, the topic has not been brought up here, so I thought I would try doing so myself.

Thank you for this amazing app! I've really enjoyed using Kore, it has improved my Kodi experience greatly.
