Multi view videos

[AmitMY]

Recently i've been thinking it would be nice to record videos from multiple angles, and package them in a single video file with multiple video streams.
I think this library, in video_to_pose should support that use case, where every video stream is taking over the people dimension, that way we could have 1 video file, and 1 pose file.
