Add FERC XBRL derived SQLite DBs to PUDL Catalog

[zaneselvans]

We now have a host of additional XBRL derived FERC databases, which should are output by the nightly builds, and should be included in the catalog, along with their metadata. JSON files can also be made into intake catalog sources, so we can provide direct access to the datapackage and XBRL taxonomy derived metadata.

In addition we should export intake catalog metadata in YAML for use with each of these datasets.
