For some DICOM sequences, the spacing isn't retrieved properly

[k5123]

For some DICOM sequences i have gotten here there doesn't seem a proper spacing information available (or it's stored differently), causing the "spacing" variable to be null, resulting in an import failure without clear error message.

The console shows:

RAM_FREE= 73786998784
RAM_TOTAL= 137357676544

code in question seems to be here:

invesalius3/invesalius/control.py

Line 992 in 66b749f

self.matrix, scalar_range, spacing, self.filename = image_utils.dcmmf2memmap(filelist[0], orientation)
