No, this does not handle spanned payload.
I have access to a sample where it looks like the packetizer got 
mis-aligned and I think
cases like those are better handled by a parser.

Adding support for multiple payload packets in one 302m packet is on my 
to-do although
the parser is better suited for that as well as the last payload packet 
might be fragmented.
