Don't throw away non-tensor objects in TensorDataclass

[brentyi]

I noticed after these lines:

nerfstudio/nerfstudio/data/dataparsers/nerfstudio_dataparser.py

Lines 291 to 303 in 368c9ec

	metadata = {"fisheye_crop_radius": fisheye_crop_radius} if fisheye_crop_radius is not None else None
	cameras = Cameras(
	fx=fx,
	fy=fy,
	cx=cx,
	cy=cy,
	distortion_params=distortion_params,
	height=height,
	width=width,
	camera_to_worlds=poses[:, :3, :4],
	camera_type=camera_type,
	metadata=metadata,
	)

that cameras.metadata was {} even if the metadata variable was set to {'fisheye_crop_radius': 707.5}.

cc @sweeneychris maybe relevant to you?

Hi @brentyi would it work if I have custom fisheye data? I tried setting the fisheye_crop_radius manually but the radius still looks like half of the shorter dimension. Any tips would be great!

@liuyuex97 I think it should work for custom data!

I saw you closed your issue, did you figure this out?
