use and document model-splitter pipeline

[madjin]

grab latest release from: https://github.com/playkostudios/model-splitter/releases/tag/3.3.0

this works for most use cases:

make LOD with 2 mesh:texture resolution variants (50% and 25% mesh, 25% and 12.5% textures)
the textures are fairly well optimized, jpegoptim couldn't compress anymore
model-splitter-cli-linux in.glb out --aggressive 0.5:25% 0.25:12.5% --force --embed-textures

test with buncha assets from hyperfy perhaps

what if settings like mesh / texture optimization could be set by user? slider possible? or maybe cooking settings (medium rare / well done). First need to gauge temperature, aka the stats of glb, so know when its adaquete enough (can use khronos 3d web commerce guidelines)
