load 3D index image

[matfallet]

Dear Segmentation editor developper, I like very much your program, thanks very much to have developped it . It is really what I was looking for with the interpolation in 3D ! The only point I will suggest to add is to be able to load an index image to create 3D ROIs inside. As a matter of fact sometimes, you just need to correct/add annotation from automatic segmentation (CellPose, StarDist,..). Thomas Boudier have done that functionnality with 3D ROI manager from 3D suite but infortunately in 3D Suite you cannot add new ROIs so both program could be great to use. Cheers, Mathieu
