Support for Logitech PTZ Pro 2

Steps to reproduce the problem:
The webcam_private api offers support for setting the absolute positions of Pan, Tilt, Zoom (PTZ) cameras. The Logitech PTZ Pro 2 we'd like to use requires these commands being send in a slightly non standard way. So currently the camera can not be controlled using the webcam_private api.

What is the expected behavior?

What went wrong?
Nothing. It just lacks implementation.

Did this work before? N/A 

Does this work in other browsers? N/A

commit 9a3bf8d9a23d254742644a5d4edab00291c7a388

Add support for Logitech PTZ Pro 2 to webcam_private api.

The camera supports absolute positioning via an extension unit (as opposed to the camera terminal unit as many other cameras do). So before issuing a v4l2 command to do absolute positioning we map the command to that extension unit. In case the camera does not implement that extension unit (e.g. all non-logitech cameras) this mapping just silently fails.
