More Hide

Added the following recipes to the Salvage Bench

• 1 Heavy Hide -> 2 Medium Hide
• 1 Medium Hide -> 2 Light Hide

As well I added the following

• 1 Heavy Leather -> 1 Heavy Hide
• 1 Medium Leather -> 1 Medium Hide
• 1 Light Leather -> 1 Light Leather

I did not add a way to convert lighter hides and leather to heavier types for balance reasons. If that interests you there are a few other mods that do that.
