Golden Hopper Mod: Stack Filtering with Golden Hoppers

About the Mod
This expansion adds golden hoppers - specialized containers with inventory filtering capabilities. Functionally they operate like standard hoppers but with one crucial addition: configurable rules for picking up and transferring specific items. The filtering implements a vanilla-style system requiring one physical sample of the filtered item rather than an abstract reference.
