Update to work with latest Webrtc/Node Versions

After a small fail on my end i started to try to get the peerconnection to run with latest webrtc and node versions. After countless hours searching and trying, replacing various changed paths, types and methods im rly stuck and am overwhelmed by hundreds of compiletime errors.

Would be nice if you could update it since my knowledge of c code is rather limited and this is a bit complex.
