    Hats: factor out the parent-choosing system.
    
    NFC, but I'm about to want to use it again elsewhere.

    Hats: choose the tiling's starting hat more uniformly.
    
    This fills in the missing piece of commit 6f75879e9fe7cb5, which was
    trying to make the output patches of tiling as uniformly random as
    possible across the whole space of possible ones. I fixed every
    _intermediate_ step in the algorithm, but forgot the starting one!

    hat-test: allow choosing a random number seed.
    
    The default one is always the same, because the main purpose of this
    tool is debugging. But one person has already wanted to use it for
    actually generating a tiling patch for another use, so let's make it
    easier to vary the randomness!
