Add configuration of uniform vs. non uniform distribution

[Ekdohibs]

Currently, all technic ores generate in a non-uniform distribution, but default ores in a uniform distribution: this is inconsistent, and can lead to people thinking some material is too rare. However, generating all ores uniformly makes mining less interesting, and creates a rainbow cave effect. I suggest adding an option to choose whether the generated distribution is optional or not. Moreover, it should override default ore generation so that default ores get generated in a non-uniform distribution if that is what is choosen.

👍 Great idea. I personally love the non-uniform ores. But the inconsistency is messing with my brain 😆

I'm working on a total non uniform ore distribution mod. I guess I'll be able to release something next week.
