We want to be able to save the transform and other functionnality applied to a Lidar.

We tried to use "Save/Load paraview state" to save all the current open sources.
But there is a bug to load a ProxyProperty (transform) of a proxyProperty (Interpreter) of a proxy (Reader or stream).
The reapply of the transform does not work and may crash when we try to access it (https://gitlab.kitware.com/LidarView/lidarview-core/-/blob/master/ApplicationComponents/lqHelper.cxx#L256)

To restore a transform we add the "Save/Load Lidar State" button to each sensorsWidget in the sensor List.
It allows the user to save some properties of the specific Lidar into a json file
or to load the properties from a json file to a specific Lidar

This commit add some messages to the user :
- An instruction message
- If an empty json file is saved.
- If there is no property to display (if the json file loaded is empty for exemple)

The properties Start and Stop of the Stream are "vtkSMProperty".
Casting it into a proxy property raises a warnings that can be confusing for the user.

The lidar state represents all the properties of a lidar source and ones of its subproxy (interpreter, ...)
A lidar source can be a lidarStream or a LidarReader.
This commit allow to save all or a part of theses properties in json file.
You can the reload them on a pipeline which already contains a lidar source
