Solves #389.

Description

This PR is an extension of OSI with two fields added in SensorViewConfiguration for Radar and Lidar to properly configure a ray tracer. One is max_range_per_ray in m that terminates a ray if nothing is hit, the other is max_range_per_pixel in m that is applied to the sum of the lengths of all rays on one path that terminates the ray propagation in case of multi-path-propagation.
