[Request]: Support for `.lcc` files in Supersplat Viewer

The [Supersplat](https://github.com/playcanvas/supersplat) repository has added support for `.lcc` files (thanks to [PR #621](https://github.com/playcanvas/supersplat/pull/621)). It would be great if the Supersplat Viewer could also support previewing .lcc files. Could this feature be considered so that users can visualize these assets directly in the viewer?
