* Use `normalized_hitobject_radius` during osu!catch buzz slider detection Currently the algorithm considers some buzz sliders as standstills when in reality they require movement. This happens because `HalfCatcherWidth` isn't normalized while `exactDistanceMoved` is, leading to an inaccurate comparison. `normalized_hitobject_radius` is the normalized value of `HalfCatcherWidth` and replacing one with the other fixes the problem. * Rename `normalized_hitobject_radius` to `normalized_half_catcher_width` The current name is confusing because hit objects have no radius in the context of osu!catch difficulty calculation. The new name conveys the actual purpose of the value. * Only set `normalized_half_catcher_width` in `CatchDifficultyHitObject` Prevents potential bugs if the value were to be changed in one of the classes but not in both. * Use `CatchDifficultyHitObject.NORMALIZED_HALF_CATCHER_WIDTH` directly Requested during code review. --------- Co-authored-by: James Wilson <tsunyoku@gmail.com>
