Incomplete lidar points cloud when sensor_tick doesn't match simulation frequency

[Paul-Nico]

Hello, I noticed a bug on the lidar sensor : if simulation frequency is higher than lidar frequency, the published lidar point cloud will only contains data produced on the last simulation tick, and will then be incomplete.
I have written a simple fix for that, which stack the produced lidar data when the simulation ticks and publish the whole packet when the sensors ticks. I would be happy to do a pull request if possible.
Best regards,
Paul

Thank you for this branch! I stumbled over this problem some months ago and you just made my day!
I also ported it to the semantic lidar. Works like a charm :)
