Even Symmetric Fan Hub Join Centreline

Gallery / Fan-out and Fan-in

A `diamond_style: symmetric` fan-out into six branches, reconverging on one join. An even branch count puts the fan's true centreline half a grid pitch off the row grid, and the fork hub agrees with the join hub on that centreline rather than landing on the nearest full grid row a full pitch away (#1595).
