Heavy Ogg duration lookup with chained streams

The search backward strategy for duration is bad as the file might be a chained stream.

see #9591 (closed)

It should at least cancel lookup if not found after 2 * i_streams * MAX_PAGE_SIZE.

A bisection search for a max_granule is probably better and would warm up seek cache.
