[rmodel] Does raylib support the Draco compression of glb format?

[AllenDang]

Issue description

As title states.

[raysan5]

raylib uses the outstanding cgltf library for gltf/glb loading and as stated on its README, yes, it supports Draco mesh compression extension but...

KHR_draco_mesh_compression (requires a library like [Google's Draco](https://github.com/google/draco) for decompression though)

[AllenDang]

@raysan5 I checked cgltf lib, it didn't mention how to enable the draco support, I tried to define a header as #define CGLTF_EXTENSION_FLAG_DRACO_MESH_COMPRESSION and added google/draco, but still doesn't work.
How to enable it?

[raysan5]

@AllenDang I'm afraid I have no idea, I never used it... I don't know if it requires calling some special function to load Draco meshes, as per my understanding, it should be internal to cgltf to process them... Maybe you can ask cgltf author for details?

I'm just updating the library on raylib with latest changes but I can't see anything related to Draco loading changes.

[AllenDang]

@raysan5 Sure, I will open an issue in cgltf to ask for it.

[AllenDang]

@raysan5 I asked in cgltf about enable draco compression, seems it's not that easy, need to inject draco decoompression into the gltf parse.

@AllenDang Thanks for the info! It seems the integration should happen at cgltf side som I'm closing the related issue on raylib. #3063
