Improvements to TCPROS protocol dissection

 - Added specific dissector for ROS Clock messages
 - Added dissector heuristics
 - Improve ROS traffic detection

Problems to resolve:
 - Some topics are mistaken for Clock messages. These includes the wheel
encoder topic.
 - ROS Services are not detected.
 - Ideally, the TF topic should be dissected as it is a very common topic
