Expanded difficulty options

[Charletrom]

Would love revisions to the difficulty system, it’s a bit stale at this point. Some suggestions:

1. Oxygen consumption

2. Generator wattage

3. Geyser output

4. Rocket fuel (higher fuel costs per hex, but larger tanks too so that range is unaffected)

The game has become more convenient than ever and I think a lot of us want more friction
