First draft of a complete CDL/SPICE netlist for the sky130_ef_io
cells (supplementary to sky130_fd_io). Previously these were black-box
stub entries. Now they make references to the SkyWater cells, although
those cells (or at least the SPICE netlists of them) are in the scratch
repository and not yet pushed to the public repository.
