A C Tun/Tap port

I’ve just open sourced my Tun/Tap port written in C. It is helpful if you want to work with Tun/Tap devices in Erlang/Elixir applications. It is also an example of writing ports for Erlang/Elixir. Please feel free to fork and let me know if you have any question. I want to make the README easy to read, so do tell me if anything confuses you. Thanks.
