running_pr_sim check in lidar always fails

[ConorEB]

Team JARVIS has been working to set up the DUST environment for testing and is happy to report that we've got all commands to work.

After debugging, it appears that line 277 in server.c (handling the command 167 for sending lidar) will always fail the backend->running_pr_sim > 0 check. From my understanding, running_pr_sim is -1 when not running, and set to 0 when it is running.

After we changed the check to backend->running_pr_sim >= 0, we successfully received lidar data as expected.
