[webrtc-extensions] On the road to HDR (#253)

youennf has just created a new issue for https://github.com/w3c/webrtc-extensions:

== On the road to HDR ==
HDR is already feasible in Chrome, at least on decoding side, with the combination of VP9-P2 and using the [color space RTP header extension](https://webrtc.googlesource.com/src/+/refs/heads/main/docs/native-code/rtp-hdrext/color-space/README.md) to provide the necessary HDR color space info.

A few things that seems worth doing to improve interop in that field:
- Standardise at the IETF the color space RTP header extension
- Mention the ability to transmit HDR in spec
- Write WPT tests

A few things that seem worth exploring:
- Should WebRTC encoded transform be able to expose/change the color space info (on receiver side at least)? Should it be left to MediaStreamTrackProcessor/VideoTrackGenerator?
- Should getUserMedia/getDisplayMedia tracks expose/allow controlling whether they are generating HDR content?
- Other shortcomings?
