    Transducer-capable refinement of the chair tiling.
    
    By separating the single 'chair' tile into three types and carefully
    defining which ones go where, I've produced a version of this tiling
    which you can make a transducer out of, disambiguating every ambiguous
    infinite supertile boundary.
    
    This is a preliminary output from a new trick I've been working on: an
    automated algorithm for developing a refined version of a tiling by
    cloning tiles based on their neighbourhood. The idea is to automate
    the process that turned hat HTPF into HHTPFFF which you can make a
    transducer out of. If I do it really well I'm hoping it could even
    turn hat H7/H8 into 10-hex and the Spectre one into 9-hex, but that's
    definitely the boss level of the idea.
    
    The code for doing that is nowhere near finished (or legible) yet, but
    it's worked well enough to get one or two successes. This one makes a
    good demo.
