[webrtc-stats] how to describe the relationship of codec and fec mechanisms (#610)

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

== how to describe the relationship of codec and fec mechanisms ==
when using chrome to make a call on
https://webrtc.github.io/samples/src/content/peerconnection/constraints/
the `inbound-rtp` codecId stat is pointing to RTCCodec_1_Inbound_96 which resolves to VP8.
However, Chrome actually wraps this in RED (historically, see https://bugs.chromium.org/p/webrtc/issues/detail?id=1467)
But this is impossible to detect using stats.

What is the proper way to deal with this? Should the codecId point to video/RED which then has an underlying codecId?
