Fixes
Add TaikoJudgementInfo.
Parse time signature from legacy beatmap control points.
Late-add the HitObjects container in the Playfield.
Subtle but looks good imo (checked with flyte).
Allows derivers to define the Content container in the constructor, to redirect the positioning of the HitObjects container.
