Changes to the techfile and netgen setup file in support of the
sky130_fd_io I/O library;  the area detection for areas of native
Vt FETs was reduced from 1um to 0.35um because the former can
overlap other areas and result in invalid transistor devices.
The netgen setup added the I/O tap cell to the cells to exclude
from matching (this change may be temporary).
