Fuel Gas World Resource Location

WHAT
Add a world resource location for fuel gas.
WHY
Because off shore natural gas is a thing and has been the main source for power and hydrogen production for fertilizers in many countries. I'd like to see it mirrored in the game as well

Just finished reading about LNG, and I do believe this is better if it's unlocked at higher tiers just from the complexity of shipping the thing alone.
Also I just noticed that the design for the fluid cargo ship is closer to an LNG carrier than an oil tanker.
