[Suggestion] Eldritch Clusters for other metals

[TechnoMysterio]

This one's a bit trickier since vanilla TC support for metal clusters is a bit spotty, but having some way to add eldritch clusters for metal types outside of the default support would be good. I'm also not sure if mods like Thaumic Integration's additional clusters are supported by the Catalyzation Chamber and the regular Alchemist's Stone, so that'd be worth checking too.
