Add research tags and datasets to metadata

Hi! I'm Niels from the Hugging Face community science team. I've updated the model card's metadata to include relevant research tags like `gaussian-splatting` and `voxel-aligned`, and linked the datasets referenced in your documentation to improve the model's discoverability on the Hub. The existing README content is excellent and very comprehensive!
