Command AH - Activate One-Push Auto White Balance (AWB) - Shutter

By sending this command via the serial communication, the shutter based One-Push AWB function
is activated. The white balance function takes approximately 3 seconds to complete. During this
time the rear panel LED will show orange.
This function operates in two steps. First the red-to-green channel difference and the blue-to-green
channel difference are calculated separately. Then the exposure times of the blue and red channels
are automatically adjusted, to obtain the same output level on all three channels.
