Generate OpenVPN split tunneling routes for video conferencing

The tool generates OpenVPN configuration commands that can be used with OpenVPN clients such as Viscosity to make video conferencing traffic bypass a Full Tunnel OpenVPN connection by making it into a split tunnel.

The output in openvpn/routes.conf can be added to a connection's config.conf file or copied into the Advanced tab under a connection's settings in Viscosity.

With some slight modifications, these routes can also be pushed down from an OpenVPN server to the end users.
