//biome needs an update

First it needs an update, the biome ids can be extended. I sent a new version to https://gist.github.com/VixikHD/241fdd02dba69f62ec91c571a305c8f8 where the original script comes from.

And maybe I use it wrong but it doesnt seems to work at all. Though I dont see on code side what could possibly go wrong, maybe it's due to subchunks
