peering submodule

[npy0]

The only example in the community right now is nanollet. nanollet doesn't need a backend at all to access data from the network. It directly connects to the network as a peer, requests for the data it needs and publishes blocks that it wants to broadcast. All directly to the network.

I want to add a submodule in the library which provide functions with which users can add this capability to their tools.

This would be fantastic @npy0 . Thanks for your library. The networking protocol is defined here: https://github.com/nanocurrency/protocol/blob/master/reference/nano.png
