Pre-built wheels for Python 3.11, CUDA 128, torch 2.7.1

[dotKokott]

Hey,

I would love the configuration:

• Python 3.11
• CUDA 128
• torch 2.7.1

To be available as pre-built wheels including the compiled cuda extensions. It seems that all it would take is to add those to the matrix in https://github.com/nerfstudio-project/gsplat/blob/main/.github/workflows/building.yml:

      matrix:
        os: [ubuntu-22.04, windows-2022]
        python-version: ['3.10']
        torch-version: ['2.0.0', '2.1.0', '2.2.0', '2.3.0', '2.4.0']
        cuda-version: ['cu118', 'cu121', 'cu124']

• Those would include the cuda extension that is otherwise compiled during import of from gsplat.cuda import _backend right?
• Can you do that or would you accept a PR from me that adds those to the matrix?
