Organise the different ways we have to visualise and analyse plasmid graphs in both pling and RH

[leoisl]

In RH, in several different scripts we analyse the plasmid graphs, e.g. :

• https://github.com/LeahRoberts/roundhound/blob/main/pipelines/build_DB/build_DCJ_graph/scripts/get_communities.py
• https://github.com/LeahRoberts/roundhound/blob/main/pipelines/build_DB/build_DCJ_graph/scripts/typing/cluster_graph.py
• https://github.com/LeahRoberts/roundhound/blob/main/pipelines/roundhound/scripts/output_explorer/view_output.py

With the common visualisation functions defined in a common lib: https://github.com/LeahRoberts/roundhound/tree/main/pipelines/visualisations/commons

pling copied this visualisation framework at some point from RH, and is used in several parts as well. But then several and important updates were done to RH visualisation framework, which are not possible to apply to pling now. As visualisation and partitioning of the plasmid graph seem to be an important common module of both tools, it seems we need to refactor this module into a third repo and make both tools use it for visualisation/graph analysis steps.
