Fix Invar material imbalance in Tinker's Smeltery alloying integration (

#174)

Invar was improperly configured to require one ingot of molten Wrought Iron and one ingot of molten Nickel to produce three ingots of molten Invar, which created the conditions for a dupe exploit.

This fixes the ratio to properly require two ingots of molten Wrought Iron instead of one.
