Postprocess where hydrogen came from

[bradenpecora]

This issue requires:

• Writing postprocessing scripts to traceback how consumed hydrogen arrived at the destination
  • Determine the locations where the consumed hydrogen was produced and the respective method of generation
  • Determine the pathways taken by the produced hydrogen to reach location of consumption
• Use the above data to create a plots for each node
  • A geospatial plot describing the pathways to that node
  • A bar plot describing the the composition of consumed hydrogen at that node
