Related to #1345, the segmentation is encoded as fractional but we currently don't load it.

Instead we throw this as an error:

Uncaught (in promise) Error: Fractional segmentations are not supported

What feature or change would you like to see made?

We should probably just threshold this to binary for now. Better of course would be to handle the fractional case as a kind of heatmap overlay.

Why should we prioritize this feature?
It's part of the DICOM standard and we have examples of data encoded this way.
