in ogg streams the raw codec data is grouped into pages, these pages are split 
over fixed size packets. The packet header allows to identify wether the page 
starts in this package or continues in the next package.

The header bits:
bitflags:
0x01: unset = fresh packet
        set = continued packet
0x02: unset = not first page of logical bitstream
        set = first page of logical bitstream (bos)
0x04: unset = not last page of logical bitstream
        set = last page of logical bitstream (eos)
