Feature request: Reset tracker on re-opening of Face Tracker source

[nerath31]

It would be great if when I return to an OBS scene with a face tracker source if I could have the tracker reset so it always re-opens back in its initial state. That way every time I return to my podium shot, it is zoomed back out and now locates the new face (likely a person of different height) and gracefully zooms in. and tracks. (Aside - love this plug-in. nice!)
