Colors of stored point cloud

[zhongyingji]

Hi, thanks to the nice implementation!

I noticed in the original gs implementation https://github.com/graphdeco-inria/gaussian-splatting/blob/main/scene/dataset_readers.py#L111, the rgb from the saved point cloud should be in range of [0, 255].

But here, the rgbs of points to be saved are in range of [0, 1] (from dust3r).

Is there any problem or I just misunderstand it? Thank you : )
