Better End Ashen Compat

Bring the End in line with this resource pack that adapts Better End to the Ashen visual style. Its woods, stones, metals, plants, chests, furniture and interfaces take on the muted, darker tones of Ashen while keeping the original Better End designs, so the new End biomes match the weathered and mysterious atmosphere of the pack.
