Grouping no longer supports large protobuf netlist

[sakundu]

Hi,
After this commit, I see the grouping code no longer supports two smaller split protobuf netlists as input as mentioned here. So I can not run the latest grouping code for the large protobuf netlist after splitting it into smaller netlist using split_proto_netlist_main.py.

Hello. @sakundu

Have you solved this problem?

Thank you.

I would suggest using that old commit (the one pointed above) to run grouping.

Thanks,
