OpenIKLayout DRC report

[kareefardi]

Description

OpenInKLayout should attempt to load DRC error reports generated by a step. It will be more convenient and ensures consistent usage of the CLI for displaying the layout at any step.

Proposal

Maybe add a CLI option or have the flow detect non empty DRC report file generated by the step it is attempting to load.

There's no way to do this without violating OpenLane 2's step strictures… https://openlane2.readthedocs.io/en/latest/reference/architecture.html#steps

@donn We may want to keep the issue open as a potential enhancement in future releases.
