In order to prevent multiple tech mods from adding multiple ores, configurable ore generation and tags should be used.
TechReborn currently hardcodes ore generation leading to a common oregen solution (such as cotton resources) to duplicate efforts. having to disable the common solution in order to use tech reborn's ores is undesirable.

Describe the solution you'd like
implement configuration file for ore generation (could even put it in the already existing world config)

Describe alternatives you've considered
Disabling the oregen of cotton resources is a workaround, but undesirable as it would then require tweaking hardcoded values for modpacks and such that rely on the same ore types

a far better solution is softcoded values and configuration files (with ore disable/enable options) to allow modpack developers to balance all mods and have a single source for oregen rather than having to manually tweak each mod's oregen separately.
