SetCallback() static private method

Connect a callback to a camera for access to the pixels. This is not recommended for display but for applications requiring access to the HAL_PIXEL_FORMAT_YV12 pixel data. The camera is selected via TangoCameraId. Currently only TANGO_CAMERA_COLOR and TANGO_CAMERA_FISHEYE are supported. The onImageAvailable callback will be called when a new frame is available from the camera. The Enable Video Overlay option must be enabled for this to succeed. Note: The first scan-line of the color image is reserved for metadata instead of image pixels.
