tidusjar b14fd36ecd #254 MOSTLY DONE! At last, this took a while.
So currently if a series exists then we will correctly monitor the episodes selected.

TODO: When the series doesn't exist in sonarr we need to add the series and then wait for the episode metadata to be populated.

Also need to add in all of the regular checks  and notification e.g. whitelist etc.
