Resolves #1.

This updates some generate scripts to work with newer builds from open_pdks/volare. Didn't encounter an assertion error about sparecell, so I opted to remove it. Please let me know if this is still needed as I plan to support additional corners (https://github.com/hansemro/skywater-130nm/tree/ff_ss_corners_rebuild).

Tested with:

This corrects the lef name of the nominal tech lef introduced by the
following open_pdks commit:
RTimothyEdwards/open_pdks@e75eaa4
It seems newer open_pdks and volare builds have already implemented this
particular hotfix. Applying this hotfix again yields invalid results, so
let's remove it.

Tested with:
- open_pdks 1.0.367
- volare sky130 build: e6f9c8876da77220403014b116761b0b2d79aab4
Automated hotfix for 183 in preparation for processing other timing
corners.
