Hoshi locations were hardcoded and only for board sizes 9, 13 and 19.
This new way has identical results for those board sizes, but
also places hoshi on other size boards.
There are no real standards for where hoshi should go on boards other
than 9, 13 and 19, but I think the results obtained are aesthetically
pleasing (and certainly better than not having any hoshi at all).
