Gabriel Wicki e01e6a567d compiler: gdsMill: Modernize codebase. 
The few Python 2 statements are replaced with their modern
counterparts.  These are one of the following:
 - print() function calls (instead of statements),
 - Exception and Error raising,
 - passing/receiving tuples as function/lambda arguments,
 - the L suffix for numeral constants.

Marti Alonso 21868f9de7 Consider spare columns when building liberty file 
Spare columns are considered as extra data bits, thus extra pins are
added. However, the data bus size on the liberty file only accounted for
the real data bits. This would cause pin size mismatch issues when using
such macros in OpenROAD and left the whole data port disconnected.

Fix it by properly setting the data bus size. Additionally, add the
spare_wen pins which were also missing.
