[Bug]: Unable to view 3d colored dicom on volume viewport.

Unable to view 3d colored dicom on volume viewport.

When I am trying to render 3d color dicom data using volume viewport I am receiving warnings stating "WebGL: INVALID_OPERATION: texSubImage3D: ArrayBufferView not big enough for request"

I have attached dummy color dicom as I cannot upload the patient data here. It should look something like this:

Issue screenshot:

Dummy Data:
dummy.dcm.zip

Steps to Reproduce

1. Use Volume Viewport API example code.
2. Upload the dummy dicom in your dicom web-server eg. orthanc
3. Use the studyInstanceUID and seriesInstanceUID for loading the metadata and the volume.
4. Run the file.
5. Change the view to axial if you don't receive the error upfront.

The current behavior

Viewport is not rendering anything

The expected behavior

Viewport should render the given 3d color dicom

So I looked at the provided data, it has a lot of metadata problems, the images are positioned on top of each other at [-50, -50, -50] and that makes our volume viewport non functional, I think our reset camera also has some problem with small image sizes (data is 18x56). If you can provide a correct data or send it to me over email I can look further ar.sedghi@gmail.ccom

I have some related fixes though #683
