add the ability to go back to pre-1.16/1.18 world, cave and ore gen

like seriously, you guys monkeying around with adding so many MASSIVE caves and essentially turning EVERY biome into a mountain range, while at the same time making it extremely tedious, annoying and time consuming to mine for ores efficiently and effectively have ruined the game for a LARGE portion of your audience that are only just now realizing how terrible your decisions were when doing the caves and cliffs updates to the game, essentially FORCING roughly half your playerbase into a singular way of playing. 

we can no longer strip mine, mob spawns are completely BORKED because of so many spawns inside the MASSIVE caves that are seemingly only a couple of blocks below the surface no matter WHERE you try to build a base, gathering ores is such a headache that so many of us end up just stop playing after a few hours because we can't find or mine anything in these ridiculously large caves that stretch from the surface down to bedrock level.

the terrain is completely FUBAR, meaning we have to spend HOURS terraforming in a PLAINS BIOME just to get enough flat area to build a small base at a reasonable Y level, and even when we get the base built, we're basically surrounded by massive mountains that shouldn't even exist in a plains biome. it's near impossible to find a desert, taiga, mesa, savanna, or jungle within a reasonable distance of each other anymore because you guys completely screwed the pooch with the biome generation..

just fix your crap or you'll end up losing players
