Use webp encode texture

[N3GIS]

Is there a plan to support the use of webp to compress textures, so that the data will be smaller

[JamesMasino]

It's possible to generate a glb off of a gltf using webp textures by editing the gltf's mimeTypes to be "image/webp" and to point towards their respective texture.webp image. The conversion errors out on any image that isn't png, jpg, or webp.
