Chapters sometimes slightly offset when using tracklist generated by mp3tag

[TheMetalCenter]

When merging from individual chapter files, sometimes time is offset by a few seconds or even up to 30 seconds. I think this is from incorrect durations when composing tracklist, mp3tag might be calculating wrong duration in some cases. Possibly due to rounding compounding.

I don't think this problem is solvable without completely changing how the chapter list is generated

Easiest way to manually fix this is to find the first chapter that deviates and decrease each subsequent chapter cue time stamp by a second or two.
