make work again with .from with groupstage instance (only supported one at the moment) - and improve on progression algorithm (now immediate from r1 to r2)
have to add helpers that was used in groupstage - may be able to factor that out or do something else, but for now copied in here
fix tests (involves commenting out some of the more specialized ones for now)
improve readability of test and also verify re-scoring
make progress instant - thus wont need limbo (will need to improve the posAry stuff though)
easier to count numplayers now as we progress perfectly
scoresBreak is only a visual property of tiebreaker now
fix res demoting and tb.uefa.test
always positionFromXarys if r1 done
