More ways to generate refined shapes#5349

I think it would be very neat to see alternative means of generating refined shapes beyond plugging a single specific shape into a bunch of trade stations, like some sort of refining machine that only works on stars/windmills, or a “merchant station” that buys shapes from you and outputs random shapes based on the complexity of the shape, including refined parts which can be filtered out. i think it’d make the last few milestones feel a lot more dynamic with how they can be approached, since much like how there’s different stackers and cutters, the player would have more than one option to create those shapes.
(also i feel like the “merchant station” idea would make for an interesting alternate mode)
