spectre_adjacent: optionally report dst_edge. Previously, you'd ask this function 'What lies on the other side of edge #i of this Spectre tile?' and it would tell you the identity of another Spectre. Now it will also tell you which _edge_ of that Spectre adjoins the specified edge of the input one. This will be used in the extra spectre-test mode I'm about to add.
