MAM Dual Shape Layer No Pins No Crystals

This simple MAM was designed to minimise the time to switch between layers. It's not very efficient in terms of amount of inputs (4 full space belts of shapes, 7 full space belts of colors) to final output (3 single lanes, 1 on each layer), and it kinda struggles when there's multiple of the same shape parts or same colored parts, but it's very quick to change over. As noted in the name it can only handle 2 layers of a shape, no pins, no crystals. Will be happy to see people improve on this.
