Patch the addon (#185)

* add new indexes, and change year column to int

* Change gist to gin, and change year to int

* Producer changes for new gin query

* Fully map the rtn response using json dump from Pydantic

Also updates Rtn to 0.1.9

* Add housekeeping script to reconcile imdb ids.

* Join Torrent onto the ingested torrent table

Ensure that a torrent can always find the details of where it came from, and how it was parsed.

* Version bump for release

* missing quote on table name
