Dicom-rs reads element (0028,0120) as an Unsigned Short, but it should have been signed.

Dcmtk output (dcmdump)

⚡ dcmdump CT000000.dcm| grep "(0028,0120)"

Dicom-rs output (dicom-dump)

⚡ dicom-dump CT000000.dcm| grep "(0028,0120)"
(0028,0120) PixelPaddingValue            US (1,  2 bytes): 63536

I'm guessing the error might be related to:

The Value Representation of this Attribute is determined by the value of Pixel Representation (0028,0103).

I have attached the file for the curious.
