Building a Distributable with GLTF Support

[Simulan]

Okay, fair. Do we then have a tool/function that will convert GLTF files to bam files, and that might be called by a handler?

I believe gltf2bam is already a CLI tool that is part of GitHub - Moguri/panda3d-gltf: glTF utilities for Panda3D so I imagine that would just need to be tied into the native build system.
