Features/change architecture to support multiples sensors in Live

Only lidar Packets were interpreted by LidarView. We want to allow LidarView to interpret other type of packets (IMU, GPS, ...)

To support live multiple sensors interpretation all network classes have to be generics (no lidar specifics).

• We extract the network part of vtkLidarStream by adding a generic Stream class vtkStream
• vtkLidarStream will inherite of vtkStream so it can no longer inherite of vtkLidarProvider
• vtkLidarProvider is removed and its lidar specific functions are distributed to vtkLidarStream and vtkLidarReader
• We need to create a generic Interpreter class to manipulate all sensors interpreters in the network
