A big refactor to the WebRTC module. API is now considered quite stable. Highlights: - Renamed `WebRTCPeer` to `WebRTCPeerConnection`. - `WebRTCPeerConnection` no longer act as `PacketPeer`, it only handle the connection itself (a bit like `TCP_Server`) - Added new `WebRTCDataChannel` class which inherits from `PacketPeer` to handle data transfer. - Add `WebRTCPeerConnection.initialize` method to create a new connection with the desired configuration provided as dictionary ([see MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/RTCPeerConnection#RTCConfiguration_dictionary)). - Add `WebRTCPeerConnection.create_data_channel` method to create a data channel for the given connection. The connection must be in `STATE_NEW` as specified by the standard ([see MDN docs for options](https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/createDataChannel#RTCDataChannelInit_dictionary)). - Add a `data_channel_received` signal to `WebRTCPeerConnection` for in-band (not negotiated) channels. - Renamed `WebRTCPeerConnection` `offer_created` signal to `session_description_created`. - Renamed `WebRTCPeerConnection` `new_ice_candidate` signal to `ice_candidate_created`
