[Outdated] Improved OGS rank histogram

@BHydden prodded me to make a proper version of OGS rank histogram. Indeed histogram from 17 months ago isn’t good at all, I didn’t put much thought into it. This time over the span of two weeks I polled almost every player who played a game within last 6 months (specifically every player who is connected through any chain of games to Sadaharu).
