[Bug] Some images render in non-radiological convention

[pieper]

Describe the Bug

When loading some data the patient's left side is shown on the left side of the screen, even though most data loads with the patient right on the left side of the screen (the latter is correct "radiological convention".

Steps to Reproduce

The issue can be seen here using data from the ReMIND collection:
https://viewer.imaging.datacommons.cancer.gov/v3/viewer/?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.207544490797667703011829289839681390478

Which looks like this:

Whereas in Slicer the data looks like this:

Note these two images are not at the exact same level of the brain, but the flip of the tumor location is the issue.

The clinical spreadsheet that comes with the ReMIND data says the tumor is on the tumor is on the patient right, so a radiology convention axial view should show the tumor on the left.

This data is unusual in the way it's been formatted.

Note that OHIF/cs3d puts the correct label (LPF) on the left side, but it is subtle and people expecting radiological convention might miss this.

The current behavior

Apparently the current behavior is to display the images closer to the way they are laid out in memory and just label them with left/right in the side annotations.

The expected behavior

My expectation is that the data would follow a hanging protocol convention to display in radiological convention.
