Corrected the PDK units conversion, which was using floor() instead
of round() and resulting in incorrect units.  Corrected the sonos
device, which was failing generation if the guard ring was not
selected.  Added options to all devices to generate vias on top of
the contacts, since it is especially important in the SkyWater
technology to get above the high-resistance local interconnect layer.
