Issue description

Having more than 1 pool in a block generation options, similarly to loot table pools. With this, you could make blocks generate at different rarities in different levels or biomes. (For example, ancient debris in Minecraft 1.16 generates more commonly below y-level 22 or gold ore generates more commonly in the Badlands biome.)
