fix No point display in stream mode
When opening a stream, no data where display on screen. This was due to:
- api change on the Stream (LidarPort -> ListeningPort)
- the stream GPS depreciated setter override the Lidar setting.
- by default the Velodyne Advanced Interpreter was used, instead of the Velodyne Meta Interpreter. This is because PV instentiate the LidarStream with the first (in alphabetic order) interpreter it knows.
