This update changes the way that 3rd party repositories are pulled,
by using (a shallow) git clone instead of pulling a tarball. That
allows the commit hash of every repository pulled to be queried and
saved in the .config/nodeinfo.json file for reference. Also in this
update: Corrected the diode device in the diode cell in the HVL
standard cell library. Corrected the build sequence for the I/O
library, which was causing the addition of the SPICE netlists for
the I/O pads to be missed.
