It is _not_ at the start of the packet (the packet flags are first,
and if it's a header packet, the codec identifier is second).

It's more than just coincidence that Vorbis has exactly 8 bits
of packet flags on all headers, of course ;)

And all this is just for Vorbis; all codecs _could_ be different
in this, there's nothing decided so far, as far as I know.
