Description

Current the ice40/utils/ice40_import_routing_from_icebox.py script imports the global nets in two different ways.

There is the `def add_global_tracks(g, ic):` function see https://github.com/mithro/symbiflow-arch-defs/blob/4mcmaster/ice40/utils/ice40_import_routing_from_icebox.py#L487-L660

They also come in through the normal `def add_tracks()` function now it can import a random grab bag of points.
