ass: use a bitmap for checking duplicate events
The loop in check_duplicate_event() essentially makes event processing
with ass_process_chunk() O(n^2). Using a bitmap instead of a loop brings
it back to O(n).
This could be interpreted as an API change: since the event list is
freely modifieable by the API user through ASS_Track public fields,
libass can't know if the internal bitmap went out of sync with the
public event list. We just redefine it so that calling
ass_process_chunk() means the API user agrees not to manipulate the
event list otherwise.
