Debug option for video generation

[neural-loop]

It could be nice to have a debug video option that would output the video with the frame number, and maybe a few other properties (if 2d or 3d modes, the x/y/z values for instance)

In auto version, there could be a dropdown for placement / top left, bottom left etc - but I don't see that as too important.

This would help for examining a video to find out where some configuration parameter threw a spanner in the works
