/*----------------------------------------------------------------------------------------------------------------------
For multichannel visualization, 5 channel max
This macro will generate a montage of composite and splited channels in one RGB Image
You can still navigate through slices or frames. 
Note : the Splitview image size can be heavy on big hyperstacks due to RGB conversion
Advice : draw a selection before running Spliview, the produced montage will be croped
The new version can ask tu user channel labels and add it in the Splitview with color corresponding to each LUTs.
