> Now that the vendor of the control can be queried, print it in
> --list-controls.
> 
> Example output:
> $ cam -c 1 --list-controls
> Using camera platform/vimc.0 Sensor B as cam0
> Control: libcamera::Brightness: [-1.000000..1.000000]
> Control: libcamera::Contrast: [0.000000..2.000000]
> Control: libcamera::Saturation: [0.000000..2.000000]
