Tools to create orthorectified image
Add:
- vtkPlaneProjector filter (to project a point cloud on a plane defined by the user or provided as input of the filter)
- vtkOpenCVImageMapper to map a 2d vtkImageData on another one
- camera mask option to vtkCameraMapper
Side effect: move getTimeSteps to a common module to avoid copy/pasting
