add cosmetic option to speedup some animations

[steven11sjf]

Game.SetSlomo(int speedMultiplier) is a lua function that sets the game speed overall (i.e. SetSlomo(2) is double speed, SetSlomo(0.1) is 1/10 speed, SetSlomo(1) will reset to vanilla speed). If we could find decent hooks for some animation start/end (i.e. the map station activation, blackout generators, that thermal vent that takes two years to drain the lava) we could add a QOL patch to make those shorter.

(I need to look into it more but it may be using these in things like CoolShinespark or the elaine slide as well)

1. this shouldnt be a cosmetic option, but instead just a normal patch option
2. wonder if for some cutscenes it might be easier / nicer to just skip them entirely, rather than speed them up.
