This time, we simplify the progress updates, aggressively mark tracks as
100 played if they are marked played_to_completion, and implement a hack
for Jellyfin spamming us with progress updates less than a second apart.
This may also be hack, but I think that if the playback position ticks
are automatically jumped to the run time ticks of the media object, it
should stop the resurrection of past scrobbles, because they will be
appropriately marked as being 100 played when the scrobble is finished.
The only weirdness here is that "in progress" scrobbles will suddenly
complete once the media type's threshold is met (90, 95 percent,
whatever). But it should be better than overwriting old scrobbles.
This commit adds a lot of files, but most of them have no impact on any
other code. The thrust here is to start creating chart pages showing
which tracks and artists were most played for various time periods. Lots
still not working, but we're getting there.
Solution is identical to what we were already doing with videos. When
looking for existing scrobbles, don't filter by completion, but just
check if the scrobble was played to completion. This does create
another irritating situation where old scrobbles from days, months or
even years ago that were not played to completion will be resurrected
and made current here. But that's way less annoying than having spam
scrobbles at the end of every track.
Historically we'd just fail if the specific MB release did not have
artwork, but this is silly. If the release itself does not have artwork,
we should also check the release group failing.
