Green Maridia check flash suits pt. 3 (West Sand Hall, etc.)

[blkerby]

These remaining rooms seemed fairly straightforward. West Sand Hall was the only one with significant changes:

• Tightened shinespark excessFrames in the suitless comeInWithSpark strats.
• Added strats that use cross-room momentum to reach the center of the room from the left. A flash suit can then be used to reach the right door with much less energy than sparking across the whole room.
• Also added a cross-room space jump strat to reach the first pillar (node 5) from the left, which can be useful even without a flash suit.

For the Insane grapple jump strats in Pants Room, I didn't try to figure out how a flash suit affects the difficulty, because I couldn't manage to do the strat even when not carrying a flash suit 🤷 So I left that as flashSuitChecked false.
