Required Info
Camera Model	D435

Issue Description

We need reigon of interest for RGB camera. is_roi_sensor() returns True for rgb sensor but get_reigon_of_interest() returns not implemented:

In [1]: import pyrealsense2 as rs
   ...: pipeline = rs.pipeline()
   ...: config = rs.config()
   ...: config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
   ...: config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)
   ...: profile = pipeline.start(config)
   ...: device = profile.get_device()
   ...: sensor = device.sensors[1]
   ...: print(device, device.get_info(rs.camera_info.firmware_version))
   ...: print(sensor.is_depth_sensor(), sensor.is_roi_sensor())
   ...:
<pyrealsense2.device: Intel RealSense D435 (S/N: 745412070033)> 05.09.09.02
False True

In [2]: roi_sensor = sensor.as_roi_sensor()
   ...: roi_sensor.get_region_of_interest()
   ...:

RuntimeError: Region-of-interest is not implemented for this device!

Hi @migel
Region of interest for RGB auto-exposure is in fact not available for the D435 cameras.
I don't think that this functionality is available at the ISP firmware level.
