SCReAM is now part of OpenWebRTC, but it needs to be enabled in the iOS SDK.

This basically involves handling the signalling and then applying it to the OWR API.

sdp.js looks for a line formatted like: https://github.com/EricssonResearch/openwebrtc/blob/master/bridge/client/sdp.js#L49

Then it sets the payload.ericscream property to true or false accordingly: https://github.com/EricssonResearch/openwebrtc/blob/master/bridge/client/sdp.js#L232

So in the JavaScript bridge code, peerhandler.js checks this value and if it is true, sets the appropriate adaptation type on the payloads' adaptation property: https://github.com/EricssonResearch/openwebrtc/blob/master/bridge/worker/peerhandler.js#L247 audio payload: https://github.com/EricssonResearch/openwebrtc/blob/master/bridge/worker/peerhandler.js#L256 video payload: https://github.com/EricssonResearch/openwebrtc/blob/master/bridge/worker/peerhandler.js#L264

The same logic needs implementing in handleOfferReceive and handleAnswerReceived. And we also need to offer ericscream in generateOfferSDP and generateAnswerSDP.
