Hitcount documentation incorrect for mania

[Yentis]

Specifically for count_100 -> these are 100s in mania, not 200s. The correct comment is already there for count_katsu which is the actual value for 200s in mania.

So in summary:

let count_max = f32::from(replay.count_geki);
let count_300 = f32::from(replay.count_300);
let count_200 = f32::from(replay.count_katsu);
let count_100 = f32::from(replay.count_100);
let count_50 = f32::from(replay.count_50);
let count_miss = f32::from(replay.count_miss);
