Remove an obsolete TODO from quic_framer.cc about changing the public
packet header format for post v32 versions. This todo was adding in
the fallout from the PAN drama. But I think it's not worth the risk
of touching the header format again so let's just leave it alone
and it'll be moot once v43 is removed.
