[Bug] Nth loader cause some slices missing randomly and sometimes becoming grey sometimes dark

[sedghi]

Describe the Bug

Seems like the Nth loader custom strategy that we have for MPR randomly cause some slices to double scale. It first seems like it is webworker and shared array buffer related but after some digging seems like it is the Nth loader.

Steps to Reproduce

• You need this PR to be merged first, since right now dicomjson is borken
• Then in OHIF open this http://localhost:3000/viewer/dicomjson?url=http://localhost:3000/wadouri.json&hangingprotocolid=mpr
• You will see some slices are

If you put a probe in the dark areas the Air is ~ -2000 HU meaning it is double scaled

The current behavior

If you replace the Nth loader with default in the mpr hanging protocol everything works fine

The expected behavior

Should not double scale
