Use github.com/pires/go-proxyproto header parsing and provide better (safer) net.Conn and net.Listener implementations. The Conn type is designed after tls.Conn. We never read more than header bytes from connection. This allows to eliminate any 3rd party readers, and to use the connection ReadFrom() and WriteTo() functions if provided. The underlying connection is available via Conn.NetConn(). On context cancellation the connection is closed to terminate the paring go routine, and to avoid unspecified behaviour caused by double reads from header parsing and user code.
