move procgen crate out of 'upcoming'
//! - **image**: conversion of 2D lattice maps to/from images
//! - **mesh**: 3D isosurface generation algorithms, smooth and cubic
//! - **partition**: spatial queries on voxels, e.g. raycasting
+//! - **procgen**: procedural generation of lattice maps, including sampled SDFs, height maps, and cellular automata
//! - **search**: search algorithms on lattice maps
//! - **storage**: compressed storage for lattice maps, i.e. functions defined on `Z^2` and `Z^3`
//! - **vox**: conversion of 3D lattice maps to/from VOX data format
