Color Space: RTP Header Extension for color space

[triggerfinger-debug]

Summary

Hello, does Pion RTP support color space RTP Header Extensions? I would like to pass HLG color space primaries, transfer characteristics, and matrix coefficients with VP9 codec.

Motivation

I would like to produce High Dynamic Range WebRTC with RTP/VP9.

Describe alternatives you've considered

It would be great if color space information could be appended and relayed to a new endpoint.
