Perform a diagonal spark to cross the sand.

Requires:

"canPrepareForNextRoom"
"canPlayInSand"
{
  "useFlashSuit": {}
}
{
  "shinespark": {
    "frames": 11,
    "excessFrames": 4
  }
}

Dev note: This is a separate strat, because the suitless bootless Evir projectile dodge is much more difficult when starting from the right side of the room.
