Suggestion: Boost power requirement for Diamond Mine in pY AE

[JStMorgan]

At present, the Diamond Mine only has a base power draw of 2MW with no extra requirements, which doesn't really match its animation of a giant mining laser breaking apart volcanic rocks. To add some extra challenge in a thematically satisfying way, I suggest bumping this power draw to a full GW, provided that the player has pY AE enabled. This would also encourage the player to interact more with the power options unlocked at late pY 2 and early Blue Science.
The power draw should maybe be left as-is without pY AE running, as I don't know the balance here!
