Challonge tournament tracking

[duckfullstop]

Right now I just overlay the Challonge web views using OBS. It'd be nice to properly integrate the Challonge API into the projector display.

Some ideas for what this could unlock:

• Page that shows matches that are waiting to be played / blocking tournament progression
• Current bracket states

It may end up making more sense to integrate this into BIGbot instead and then using the bridge to get the information to this bundle as required.
