Updated foundry_install to change the recent "hide" option addition to a more
general-purpose "lefopts" for passing "lef write" options to magic. With this,
and with an update of magic, new LEF views of all standard cells are now generated
that are all consistent and do not depend on the SkyWater LEF sources except for
annotation. LEF views of selected I/O cells were edited to remove DRC errors and
for the bus filler cells, to remove the obstruction layer from the area typically
used to drop additional cells into the padframe.
