• cleanup csi_camera_stream node => should be a inference node for pothole detection
• verify the command_centre topics are OKAY
• change potrider serial control topic name from /JSON to a better name
• change topic names in command centre (remove the /rover prefix
• remove waypoints topic from command centre, change swdata topic to gps_waypoints
