Commit Message

ENH: Adds support for supplementary asset mappings (#1612)

* ENH: Adds support for supplementary asset mappings

- Adds a supplementary_mappings table to the assets.db, to hold point-
  in-time mappings of sids to arbitrary categories of values, e.g.
  alternative identifiers. This bumps ASSET_DB_VERSION.

- Adds supplementary_map and supplementary_map_by_sid to AssetFinder,
  caches of the underlying table that are fully populated on first
  access, which map the supplementary values to sids and vice versa,
  respectively.

- Adds lookup_by_supplementary_mapping method, which fronts
  supplementary_map to query for the asset last known to have held a
  value at a given dt.

- Add get_supplementary_field method, which fronts
  supplementary_map_by_sid to query for the last known value held by an
  asset at a given dt.
