feat(geomath): introduce class for point cloud

[kschrab]

Description

Adds a new class representing a Point Cloud. This class can serve as a future common class between PHABMACS or CARLA (producers of point clouds) and MOSAIC Application (consumer).

• Based on the class LidarFrame, which is currently placed in the PHABMACS simulator.
• PointCloud itself is abstract, and must be created using the inner implementations Relative or Absolute, depending on the format of the hit points (either in absolute or relative coordinates).
• PointCloud contains single points based on Vector3d coordinates. Each Point has additional fields distance (distrance to origin of point cloud) and hitType (type of object being hit by the ray which produced the point, with 0 = no hit).
