Add Stager for SB Factory

[AardWolf]

This is an opportunity to use the new stagers! We could add stages for the SB Factory using a mix of the existing logic and adding in logic for Factory Repair Charms (FRC). This would mean we'd need a "+ Repair" for each stage. For clarity we might need something to indicate the stage is without repair charm hunts when appropriate.

I would love to help with this issue!

A big question around it right now is whether we really want "repair" stages or not - and how to indicate a hunt did not have FRC when it did not. In the past we've run queries against the database to get the information desired (drop rates, ARs) broken out further than what MHCT has in its summaries so far.
