The Hundred's five-ball overs reach every figure this server computes

BallsPerOver was a constant six, so a Hundred state was reasoned about as
120 deliveries when only 100 exist — balls left ran ~20% high and the win
model overpriced every chase. MatchState carries balls-per-over (six unless
set), live Hundred matches stamp five automatically off the league name,
and cricket_win_probability accepts balls_per_over for hypothetical states.
Same fix as cricketfornoobs.com; ported hunk for hunk with its test.
