Description

Currently the way to get a real rr_graph is to use the [ice40/utils/ice40_import_routing_from_icebox.py](https://github.com/mithro/symbiflow-arch-defs/blob/4mcmaster/ice40/utils/ice40_import_routing_from_icebox.py) script.

However, it would be much nicer if we could generate the routing without needing icebox. The script at [ice40/utils/ice40_generate_routing.py](https://github.com/mithro/symbiflow-arch-defs/blob/4mcmaster/ice40/utils/ice40_generate_routing.py) starts doing that.
