Barrier crystal

[PIXELATOR37]

When touched, it'll trap the player in crystal prison, making them invincible (except to pits, crushing, and rising/sandwich lava) but unable to move until they dash out of it; it'll also give at least one dash when touched, to avoid softlocking the player because they can't dash out of it. We might want another "barrier" entity that will break the crystal automatically, for dashless maps. Sprites are in objects/VortexHelper/barrierCrystal
