feat: ECP-126 Add measure and scale level graphs for parents by language

WIP: refactor so multiple graphs can be defined for a given slug

WIP: fixed scale view but broke 'All Parent' graph

WIP: working state.  All views working properly

WIP: Refactor graph_map into two collections; measure_level_graphs and scale_level_graphs

WIP: refacter GroupedBarColumnPresenter to accept a 'construct' instead of specifying measure or scale

WIP: fix scale graphs being shown on incorrect view

WIP: Merge parents_by_language class with parents_by_language_by_scale so it can handle display of both measure-level and scale-level graphs
