I made some multiplayer rankings.  This is a help when setting up games, to decide if teams are fair. First, these rankings depend on replays (specifically, metadata.json files).  If you'd like to improve or expand these ratings, zip up all your a21 replays and send them to me!  Check https://trac.wildfiregames.com/wiki/GameDataPaths to find where they are on your computer.   I have revised these rankings several times as I get more data and improved methods.  See the spoiler belo
