Remove ordering by sequence 

This was used for Chaturbate, because the filename format was known.
With several camsites the filename format can differ and this is not a
good solution anymore. Instead we now just sort filename. To make sure,
the files have the right order, HlsDownload now creates a prefix for
each segment.
