bug in code

[vixtor-qm]

Hello, i have found a bug in the code that leaded to a crash of the entire node.

leddar.cpp:

line 39: it should be

 LeddarGetDetections(handler, detections, BEAM_COUNT); 

instead of

  LeddarGetDetections(handler, detections, sizeof(detections));

See original LeddarCDemo.cpp
They pass number of readings instead of actual size.

It might have changed since I've used it. The code you see in leddartech.cpp is a copy of Leddartech's code on which I've added some code to convert the data to ROS laserscan message. You can see the original version of the code here (when I uploaded it to github): https://github.com/jpmerc/leddartech/blob/75f2cebe8f435c01e1983fb2c13a38fd65d519c0/SDK/LeddarCDemo/Main.c

I don't have access to a leddar anymore, so I suggest you to do a pull request with the working version and I'll merge it.

Thanks!
