Can I have a private option that prevents resetting readorder on flush?
In my own code, I don't want to delete the libass event list on seeks.
On the other hand, libass will use readorder to deduplicate events. So
if libavcodec outputs packets with the same readorder, they will be
incorrectly dropped.

Unfortunately it looks like this would have to be implemented in every
decoder, which is not practical.
