Found a potential issue with file locking in magic when working with the
I/O pads, which can open enough simultaneous files to exceed the file
descriptor limit on some OS variants. Also: Reduced the "gpiov2_pad_wrapped"
file to only contain the SkyWater cells by reference, and not redefine them,
which is both unnecessary and puts a large GDS file into the repository.
