IGD 2.0 support

[canndrew]

Ever since the add_any_port method was added this library has had some support for IGD 2.0 although it by no means supports all the IGD 2.0 methods (or all the IGD 1.0 methods for that matter).

[marco-c]

A first step would be to search for IGDv2 devices too (and then use the v1 methods). This would be useful if there are IGDv2 devices that respond to a IGDv2 search and not a IGDv1 one.

@marco-c I think I've got such device. What's interesting is that it's SSDP response is:

which clearly states that version is actualy 1

urn:schemas-upnp-org:device:InternetGatewayDevice:1

But then $ curl http://192.168.1.254:5000/rootDesc.xml returns

Where you can find

urn:schemas-upnp-org:service:WANIPConnection:2

And because of this rust-igd fails to find IGD device on LAN. But such a simple patch fixes discovery and the rest works smoothly:

[marco-c]

Since IGDv2 is backwards compatible, I think your patch should be safe. urn:schemas-upnp-org:service:WANPPPConnection:2 should probably be added too.
