When using paged / LOD streaming (paged: true) with SplatMesh, the user-provided options.fileType is ignored and not passed to PagedSplats.
However, in many real-world cases:

• The download URL does not include a file extension (e.g., signed URLs, dynamic download endpoints, CDN links)
• We cannot modify the URL to add .rad or other suffixes
• The automatic getSplatFileTypeFromPath fails to detect the correct file type

This makes Paged / LOD streaming impossible for such files, even though we know the actual file type in advance.

Please add support for explicitly passing fileType as an option to SplatMesh and PagedSplats, so users can manually specify the file type without relying on URL path parsing.
