Output a list of fastest races in a league

Database info:

matches maps to multiple races via match_races (on match_id)
matches links to racers and cawmentator:
	matches.racer_{1,2}_id
	matches.cawmentator_id
races contains start time:
	races.timestamp
races maps to multiple runs via race_runs
race_runs contains time for each racer
	race_runs.time: centiseconds
	race_runs.rank: 1 for fastest time
