[ndnSIM] Full name requested, but Data packet does not have wire format (e.g., not signed)

Hi,

encode the data before sending the packet out:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp#L128 <https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp#L128>

Thanks,
