Skywater changes.

Default 1 thread and no temp subdirectory.
Add skywater setup/hold golden data
Add CLI option for simulation threads (-m)
Add compatibility mode option and nomodcheck for ngspice to speed up sky130 model loading.
Make subdir when using default /tmp dir.
Pass num_threads so temp subdirs are created.
