Updated the sky130gds.tech file to include an assortment of DRC
checks that the DRC deck in the "standard" sky130.tech file does
not do.  Added off-grid checks as well as basic checks on implant
layer geometry.  The off-grid checks require the most recent
version of magic, so the "requires" line was added to the tech
file.
