Jędrzej Stuczyński aee3286793 Feature/packet chunking (#158)
Basic support for message chunking and reconstruction. It's now possible to take arbitrarily-sized input and send it through the mixnet. The sending Nym client will automatically chunk the input into Sphinx packets, and the receiving Nym client will then reconstruct the message at the other end.
