Enable aggregation of reshaped FERC DBF/XBRL data

[zaneselvans]

Organize the per-row/col IDs compiled in #2015 such that common / useful aggregations of the reported financial data can be recreated programmatically.

current issues from convo w/ @e-belfer & @zaneselvans

from the inter-dimensional cram!

• a special case of adding calculations to link the same xbrl_factoid that shows up in two tables: when one side of the calculation only applies to a particular dimension. for this we may need:
  • the ability to hold multiple calculations for one factoid (pick the leafier other dimension)
  • additional keys in the tree/forest
• when xbrl_factoid names are the same in different tables but that only applies w/ dimensions
• first hole chunk of plant in service table
• zero source_tables. need to fix that.

from tree forest cram!

• mutli-source_table names creating non-tree-like structure.
  • if linked to a pass-through calculation, that's fine. we can remove a 1-parent-to-1-node
• found one instance of dbf_only facts that weren't adding to the metadata. small set of other missing dbf_only (typically in older years they reported w/ less granularity)
• w/ pass-through/pointer calculations connecting factoids i
• some nodes have more than one parent. remove an edge node
  • only if the weights & tags are the same.
  • get rid of middle-man nodes
