Oni Production Techniques

Adds various strong stuffable materials exclusive to the oni race. Most of which are available from the lowest tech level. All of the added resources require some amount of oniamine to make.

Revanant Leather
@ A very strong leather equivilant to thrumbo fur
@ Requires a lot of oniamine to make
@ Can be made at a crafting spot or a biofuel refinery

Oni steel
@ Its pygnite but stronger
@ Can be made at a smithing table or a smelting table

Oni wood
@ A wood type that's more durable and better for blunt weapons, at the cost of being super flammable
@ can be made at a crafting spot or a biofuel refinery

I just wanted to give the oni a bit more use outside of drugs. I may add some unique weapons later.
I did not make the oni mod, it was made by Tarojun
