Overhaul of the sky130 I/O pads.  With a few fixes to the magic tech file and
a few non-physical-mask changes to the vendor I/O cells, the I/O cells will
now read into magic in a way that they can be extracted from either GDS or
.mag views, and will pass LVS against the provided SPICE netlists, and will
be simulatable.  Important note:  Swapped the GDS purpose of "text" vs. "pin"
in the magic tech file so that it now matches the foundry use (previously it
was defined to match the foundry documentation, which was in conflict with
the foundry usage).
