This commit adds the rest of the support for actually being able to use
Overdrive MediaMarkers.
Shoutout to benonymity's project OverdriveChapterize, where I was able
to port over the logic to actually do the timestamp conversions
https://github.com/benonymity/OverdriveChapterizer/blob/main/chapters.py
I still need to do a lot of cleanup of the actual code, and finish the UI.
This commit updates the logic in
generateChaptersFromOverdriveMediaMarkers to create a single array of
objects that holds all of the clean MediaMarker data. it still needs to
be conveted to the NewChapters format.
I should also rename this function to "cleanChaptersFromOMM", but I"ll
do that later
Initial client side support. Still a good amount to do. Specifically
around actually parsing out all of the media markers, and generating a
single chapter object that can be applied
