Description

OpenROAD supports stopping detailed routing and resume it. In complex designs, doing so and dumping the layout would be useful to study the design and learn about routing issues

Proposal

Create an additional step that does so

At the moment, OR supports saving a snapshot of the layout after each DRT iteration - along with drc report. However, they don't seem to officially support pausing and resuming the DRT. For now, I will create a PR to save snapshots since this has proven useful in recent projects.
