LIDAR only autonomous flight

Our code stack also supports LIDAR-only sensing mode (i.e. no camera is needed).

This feature is still under development. It works but is not as robust / well tuned.

The LIDAR will be used for both odometry and mapping (obstacle avoidance). We have done some initial tests for autonomous flight with LLOL: Low-Latency Odometry for Spinning Lidars, and check out to this commit: 6fafc5d872d99f34ca30de39b6885d2bb880797c. Currently, we're using the feature/lidar-odom branch for developing this feature:

If packet jumps for exactly number of columns you specify in ouster_dedocer.launch, then go to http://YOUR_LIDAR_NETWORK_HOST_IP(e.g. 192.168.100.12)/config and change "UDP Profile Lidar" to LEGACY
