opus reset decoder on seek completion to prevent stack overflow

Browse source 
apparently we should be doing this anyway

mark4o> The packets overlap and may reuse state set by other recent packets,
        so if you seek to a different position,
        resetting the state helps to ensure that the subsequent
        packets won't use the state set by the unrelated packets
        that were processed before the seek.
