Bug (localize_3d) - error when pyHiM try to segment reference RT image

[XDevos]

The problem should come from ~image_3d_0 = reinterpolate_z(...) inside segment_sources_3d_file method.

parameters.json:

"barcode": {
    "segmentedObjects": {
        "3Dmethod": "thresholding",
        "reducePlanes": false
    }
}

terminal:
