Re: [webrtc-pc] Not clear how to set # of layers when answering an offer with a track

We currently send offers including a=simulcast from our SFU to Firefox:
```
a=rid:hi recv
a=rid:mid recv
a=rid:lo recv
a=simulcast: recv rid=hi;mid;lo
```
Works fine and there must be a way to indicate support for receiving simulcast streams (rid should be covered by the extmap line). It is somewhat ugly since we still need to then call sender.setParameters with the target bitrates and scaledown ratios we want and basically have to hardcode the rids.
This wouldn't be drastically different from adding the transceiver before setRemoteDescription with the hardcoded rids though.
