Max Kellermann e0d5ee0045 decoder/flac: calculate time stamp from current frame 
Don't update a float timestamp, this will make imprecisions add up
after a while.  We already have the number of the current frame, let's
just calculate the float timestamp from that for every decoder_data()
command.  For this, we need to add the attribute "first_frame", for
CUE sheet songs.
