getBytestream()

char * DataPacket::getBytestream	(	unsigned	bytestreamNumber,
		unsigned &	byteCount
	)

Verify that packet is correct type

Check bytestreamNumber in bounds

Calc positions in packet

Sum size of preceeding stream buffers to get position

Double check buffer is completely within packet

Return start of buffer

verify()

Verify header is good

Calc sum of lengths of each bytestream buffer in this packet

Calc size of packet needed

If needed is not with 3 bytes of actual packet size, have an error

Verify that padding at end of packet is zero
