NAV310 - Optimized support for parameter settings in launch file

[michael1309]

The NAV310 is a lidar optimized for navigation. In order to ensure functional reliability for the application, not all parameterization that a ranging lidar offers is therefore supported. In order to increase the transparency for usability here, the following is proposed:

• Specify restrictions in the launch file
• Remove parameters from the launch file that cannot be set in a meaningful way (e.g. start angle, end angle).
