Can't export screenshots in EXR format from Python

[duklin]

When running

python scripts/run.py \
    --scene /path/to/transforms.json 
    --load_snapshot /path/to/snapshot.ingp 
    --screenshot_transforms /path/to/transforms.json 
    --screenshot_dir /path/to/screenshots 
    --width 256 --height 256

I get an error

Traceback (most recent call last):
  File "/home/duklin/repos/instant-ngp/scripts/run.py", line 284, in <module>
    cam_matrix = f.get("transform_matrix", f["transform_matrix_start"])
KeyError: 'transform_matrix_start'

Also, there is no progress bar and no support for exporting the screenshots in exr format.

This is now fixed with #1421

Have you solved the KeyError: 'transform_matrix_start' problem yet?
