JamesJCode 5187ea721d Implement within_diff_pairs and group_matched DRC skew arguments
Enables DRC to calculate skew based on new arguments to skew
constraint DRC clauses:

Using (group_matched): calculate skew across all matching nets
Using (within_diff_pairs): calculate skew within every diff pair
   found within the matching nets

Additionally fixes DRC skew calculation to calculate skew relative
to the longest net in the skew check set (in line with PNS meander
placer calculations).
