Change userBeatmapOffsetClock to a FramedOffsetClock

Browse Source 
Assuming that the global audio offset is set perfectly, such that
any audio latency is fully accounted for, if a specific beatmap
still sounds out of sync, that would no longer be a latency issue.

Instead, it would indicate a misalignment between the beatmap's
track and time codes, the correction for which should be a
virtual-time offset, not a real-time offset.
