Correct handling of block orientation in block.py & macro.py.
* Bug: In cumulus/plugins.macro.Macro.__init__(), stick out the rigth number
of pitches on North & East sides (never tested before).
* New: In cumulus/plugins.macro.Macro.__init__(), manage layer change
if the terminal is not in the preferred routing direction. Use BigVia
and put at least two cuts.
