Revised release for submission for Udacity testing. Includes the following improvements:
- Increase waypoint follower pure pursuit min lookahead distance to 6m to reduce initial steering correction amount
- Pass images into a deque to keep up to 3 images ready for processing by classifier to increase number of light state detections
- Extract waypoints from Carla site test data to confirm steering response is still enough to follow the turn around the course
- Improve RViz visualization for site test including LIDAR point cloud and rescaled markers
