Requires:

{"getBlueSpeed": {"usedTiles": 40, "openEnd": 1}}

Dev note: The longest necessary runway for blue speed is less than shinecharging, because while shinecharging Samus slides after pressing down, and then typically needs to jump again. This helper can be used on strats with a shorter than 40 tile runway, if Samus just needs run through an enemy or speed blocks (as low as 32 tiles is expected in vanilla).
