[noise] nyquist - Yet another Noise Protocol Framework implementation

[Jason A. Donenfeld]

Hey Yawning,

Nice work. If you're interested, WireGuard has test vectors using a
few of the Noise libraries. Here's an existing one in Go:

Perhaps you'd like to see if swapping out titanous' implementation for
your own in here can still complete a handshake and exchange pings
with the WireGuard demo box.
