Add support for GLTF KHR_texture_transform extension

[tonpix]

Describe the bug If tiling for texture is set 1 in blender, exported .glb is viewed correctly in F3D (mesh and viewport grid are visible). If I set tiling higher than 1, F3D viewport is empty - no visible mesh or grid, despite file size indicating there's mesh data inside.

Tiling set at 1:

Tiling set at 2:

To Reproduce

1. open invisbleMesh.glb https://drive.google.com/file/d/1OSo28XK-DHT4vItJ1mqeSOTo_UuriRIR/view?usp=sharing

Expected behavior Visible mesh+viewport grid.

Can you parse the logs when using the --verbose option? I suspect setting the uv scale will produce GLTF files with the texture transform extension

Indeed that's the problem. Related issue: https://github.com/f3d-app/f3d/issues/608
