Biome extension

Vanilla Expanded Framework has this following mod extension to manipulate biomes. Currently it contains a terrain swap feature which used if you want to replace some terrains, like gravel or sand, during the generation, an option to change the color of the fog of war, a few options to change how rock types are generated, and an option to skip certan gen steps like ancient debris. Example of usage:
