SOG to Splat Converter

PlayCanvas SOG stores Gaussian parameters packed inside WebP texture atlases sorted by Morton code. When you want to use a model in simple Three.js scripts or legacy WebGL shaders that only know how to read flat 32-byte chunks, converting from SOG back to .splat unpacks the textures into linear memory.
