updates to camera nodes

[arthurcorrell]

General changes:

• added topic for camera_node to publish to, i use foxglove to vis image topics
• made detect_objects service return all detections, the behavior tree in the 'cortex' pacakge handles that
• added cameraCompressed to setup.py as camera_node_raw, is run with a timer callback
• added runtime parameters to config these settings, left them at their default values (see Camera.md)
