Render video on image anchor

Given resource constraints on Android, the goal is to display artwork with an image anchor and the video file.

Background

@dulimarta opened an issue ~2 years ago SceneView/sceneview-android#144 (comment) that hasn't been resolved. However, a video implementation may be straightforward based on a comment in the SceneView Discord:

Didn't had time to bring back the VideoNode. If you want to make it... You just need to do exactly the same as ImageNode (extend PlaneNode) and use a video texture instead of a the image texture. Might not be long but please share it with others in Sceneview

Going to go with the last version of the Sceneform library (https://github.com/SceneView/sceneform-android). If push comes to shove it can be forked to keep the deps up to date.
