PTZ Control to override face tracking movement

[abelcruise]

There are times we need to control the camera manually, but the face tracker will always try to correct it. It would be helpful if the ptz control plugin can override the controls. Thanks!

There are no API on obs-ptz to find there is a user-input. At first, I need to ask obs-ptz to have a signal to notify when user has clicked the buttons.

As a workaround for now, I've added a Pause button on the Face Tracker Dock so you may pause this plugin.
