Create a Tool (pcli or otherwise) that can read events from PCES and show them in the HashgraphGui

Sometimes we need debugging production scenarios, and we can access the pces files + the snapshot and maybe the roster.
We already have support to take those events from production, slice them so we have a subsection of the graph that we are interested in, rehash and resign the events using a new roster, so we can debug how the events go to consensus.
We need also to make debugging even easier, a tool that after running those events through a pipeline, show the graph in the hashgraphGUI

Start by locating the existing pipeline that reads PCES files, snapshots, and rosters, including the event slicing, rehashing, and resigning steps. Then inspect how HashgraphGUI accepts graph data; done means a pcli or equivalent tool can pass processed events through the pipeline and display the resulting graph in HashgraphGUI.
