             Enable camera image rotation, rotate the camera image to the correct orientation.
             - On ESP32-P4, rotation is handled by PPA hardware.
             - On other chips, rotation is done in software with performance cost.
             - For 180° rotation, use HFlip + VFlip instead of this option.
