Tiny MAM Brain - MAM-ready shape un-stacker logic

[1.0+ only] Modular logic which unstacks shapes and tells you the colour and shape-type for each corner. It turns each corner into a full shape which makes MAM-inputs easier. It also detects crystals and instead outputs a pin letting it stack and crystallise correctly later. correctly outputs nothing for empty corners. Not included in blueprint but outputs of adjacent modules can be AND together for empty corner detection for bypassing stackers. You can easily remove the 3x3 chunk at the end of each module which filters out crystal outputs if you want to deal with that somewhere else.
