Draft: [fix] Fix and enhance vtkLidarKittiDatasetReader

vtkLidarKittiDatasetReader was not working after changes in the vtkLidarReader it depended om:

This MR:

• removes the dependency on vtkLidarReader
• makes sure that Kitti reader can be used from the menu Advanced > Open > select the folder
• removes the need to specify the number of leading zeros in filenames
• fixes the hypothesis on the azimuth value (starting from the back of the vehicle as in Semantic Kitti)

TODO:

• add test
