Add std::optional<RtcpFeedbackType> MediaContentDescription::preferred_rtcp_cc_ack_type()

This method returns the preferred feedback format to use for a certain media type. This is used to decide if CCFB should be enabled or not.
Also, if a feedback type is decided, this is propagated to Audio Send stream in order for the stream to be aware of if it should be part of BW allocation.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See here for instructions on how to get started developing with the native code.
