Leatherfuel
Create burnable "logs" from patchleather. Can be used as "Woody" stuff, but the stats are about half of actual Wood.
Leatherfuel can also be converted to chemfuel (but less efficiently than wood).
Patches all Core wood-fueled buildings to use this as fuel (along with wood).
Compatible with "Primitive Storage": Woodpile
