Detailed Description

Reads, writes, and removes QuickTime-style chapter tracks from MP4 files. A QT chapter track is a disabled text track (hdlr type "text") referenced by a chap track-reference in the audio track's tref box. This format is understood by QuickTime, iTunes, Final Cut, Logic, DaVinci Resolve, Twisted Wave, and most other Apple/macOS software.

The existing MP4ChapterList class handles Nero-style chpl atoms, which are a different (and less widely supported) chapter format.

Chapter times use the same 100-nanosecond unit convention as MP4ChapterList so that existing Chapter / ChapterList types can be shared.
