inria encoding crashes

[Derk21]

Write file operations of formats "3DS-INRIA-ply.yaml" fail because opacity is of shape (num_primitives, 1) and isn't squeezed like in write_image.

Also the configs aren't found

reproduce bug:
python3 -m ffsplat.cli.live --input {path to point_cloud.ply} --dataset-path={path to dataset} --input-format=3DGS-INRIA.ply --verbose

in viewer, click on "convert", select format "3DGS-INRIA-ply.yaml", click on convert

Error:

Also there is inconsistent naming that is causing another error, when using ffsplat.cli.convert:

python3 -m ffsplat.cli.convert --input={path to point_cloud.ply} --input-format=3DGS-INRIA.ply --output-format=3DGS-INRIA.ply --output={ouput path}
