SM crush bonus change

[Migratingcocofruit]

What Does This PR Do

Changes to SM's crush bonus to be proportional to the EER and the moles of each gas in the chamber. The modifiers for each gas are:

• O2: 1.15 EER at 11333 Moles per tile
• CO2: 1 EER at 11333 Moles per tile
• N2/N2O: 0.55 EER at 11333 Moles per tile
• Plasma: 4 EER at 11333 Moles per tile

Why It's Good For The Game

Crush is an uninteresting mechanic, just a flat boost to power when a certain amount of gas is in the chamber. It does carry some risk in cases where the engine delams, but usually crush setups mitigate that to begin with just due to how difficult it is for them to be set on fire. In addition, the N2 crush setup offered too much reward for too little risk, being the equivalent of a 7000EER engine without the arcs, anomalies and gas generation.
Changing to bonus that is also dependent on EER, and gives greater bonuses for more dangerous gasses should reward risk better as well as give more room to experiment with interesting gas mixes to try and optimize the different parts of the equation.

Testing

• Messed around with different gas mixes and observed the expected power boost in the debugger.
