Added a couple of missing rules to the magic tech file for sky130
regarding the distance of N-diffusion and P-tap to high-voltage
nwell, and for high-voltage N-diffusion to any (high- or low-
voltage) nwell.  In most cases these rules were effectively checked
by other rules, but near deep-nwell edges in particular, the nwell
edge can be too close to diffusion in pwell without being flagged
as an error.
