Suggestion: add visual indicator in HUD for Flesh Melter stacks

I know Flesh Melter artifacts aren’t really used all that much rn but I still think it would be helpful to know just how many stacks and how much extra damage we’re getting at a given time. There are definitely other gear-based abilities that could be shown in the HUD as well but Flesh Melters in particular could use it since they use a stack mechanic.
