MoviePipeline: DWAA compressed EXRs don't support 32-bit images

1. Create a basic MRQ sequence and job.
2. Add the EXR output setting instead of JPG. Change the compression to DWAA
3. In the Deferred Pass, enable 32-bit Post Process Materials, and enable the first element in the array.
4. Render
5. Open the resulting exr file in Nuke and switch to the secondary layers (WorldDepth) and note that all the pixels are black.
6. Change the EXR compression back to None and re-render
7. Reload the image in Nuke, note that the pixels are now non-zero
