Corrected the area parameter for bipolar devices in the extraction
deck for magic for sky130. The wrong terminal was being used for
output of the area (collector instead of emitter), and since magic
was unable to calculate areas and perimeters of terminals on planes
other than the plane of the device identifier, this error was not
noticed. With the most recent version of magic (version 8.3.402),
bipolar and diode areas are now computed correctly for the sky130
PDK.
