Pre-1.17 Ore generation above y-level: 0

[Shadymitsu]

Hey there, I have been doing some reading and playing around with the plugin and am wondering if it would be possible to configure it in this way:

y-level: >0 = Ores generate as they did pre-1.17
y-level: ≤0 = Ores generate as they currently do in modern vanilla Minecraft.

I may not fully understand how this works, but from what I can gather ores which have a deepslate variant can't have their generation height changed individually (e.g. Can't adjust the generation height of diamonds to y: 0 - y: 15 without stopping deepslate diamonds from not generating below y: 0)

If this is possible and I just haven't understood how it is achieved, would you mind explaining how to achieve this?

Also, is there a way to change the "best y-level" per ore.

For instance, y: 11 was the "sweet spot" for Diamonds pre-1.17

Many thanks, and great work on the plug-in!
