Added material cutting to my voxel renderer.
A sphere gets moved along a 3D path to cut out material from a root voxel (you cannot see the sphere currently, only the cutted geometry).
If I'm not mistaken, this created 1.3 billion leaf surface voxels, or 21 million leaf bricks each holding 4x4x4 leaf voxels.
The cutting took ~3 seconds using 12 threads on my Ryzen 9950x CPU. I will try to further improve using SIMD or GPU.
