[ANN] Enumlib.jl: a package for derivative structure enumeration

Most users of my original enumlib will go on calling it (this new code) from inside Python, obliviously—so this probably appeals only to a handful of computational materials scientists here. But it is the culmination of a couple of years of careful work, and I would rather it be findable than not. Enumlib.jl generates the symmetry-distinct supercells and atomic decorations of a parent lattice—the building blocks for cluster-expansion fits and configuration sampling in alloy theory. It is a from...
