Keep EXT_mesh_gpu_instancing when running gltfpack

[BoyBaykiller]

I am running gltfpack -v -mi -noq -tc -i .\SimpleInstancing.gltf -o .\Compressed\Output.gltf over this gltf model.
It uses the EXT_mesh_gpu_instancing extension to define a bunch of instanced cubes. I can render it correctly as it, but after running it through the command the EXT_mesh_gpu_instancing extension is removed, resulting in only a single cube being rendered.

Am I missing something?

gltfpack currently doesn't support EXT_mesh_gpu_instancing in the input scenes (see https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md#extensions for full list), but this is on a short list to add support for.

Oh my bad for not seeing that. Thanks, and I look forward to it being supported!
