Requires adjusting [lightsClosestHit](https://github.com/gkjohnson/three-gpu-pathtracer/blob/main/src/shader/shaderLightSampling.js) to traverse multiple light hits and accumulating all lighting contributions from hit lights.
To be used for validating the behavior of different sampling functions at different intervals

Currently even when it's set to 0 intensity it takes samples. related to #141
- attenuation / absorption - subsurface scattering - can be used for fog? - variable density fog / volumes? - 3d textures - ray marching See - https://github.com/KhronosGroup/glTF/blob/main/extensions/2.0/Khronos/KHR_materials_volume/README.md - https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_transmission/README.md...
