Corrected the netgen setup for sky130 (again), as previously the
"pj" parameter for the low-level diode model was replaced with
the "perim" parameter for the diode subcircuit model, but the
"perim" parameter remained in the list of parameter names to
delete, and so was always ignored.  Fixed by removing "perim"
from the parameter delete list for diode devices.  Thanks to
Mitch Bailey for bringing up this issue.
