[Doc] Clarification on overlapping non processed cloud packets

[bertulli]

Hi, thanks for your work.

We are using a relatively slow CPU (single threaded, ~700MHz) due to power saving, and we integrated in our system two SICK PicoScan150. I couldn't find any information in the documentation: what happens in cases like this?

Here, you see that the frequency at which the LiDAR is sending data point clouds to the CPU is much higher than the frequency at which the CPU is processing them. When the CPU finishes the first processing and receives the cloud 10, what happens? Does it process cloud 10 (dropping packets 2 to 9), or cloud 2 (and then 3, and so on)? Since our use case requires to process cloud 10, and simply skip the intermediate ones, do we have to implement a manual check?

Thanks!
