// Used to group RTP transports between a local endpoint and the same remote
// endpoint, for the purpose of sharing bandwidth estimation and other things.
// Comparing this to the PeerConnection model, non-budled audio/video would use
// two RtpTransports with a single RtpTransportController, whereas bundled
// media would use a single RtpTransport, and two PeerConnections would use
// independent RtpTransportControllers.
// RtpTransports are associated with this controller when they're created, by
// passing the controller into OrtcFactory's relevant "CreateRtpTransport"
// method. When a transport is destroyed, it's automatically disassociated.
// GetTransports returns all currently associated transports.
// This is the RTP equivalent of "IceTransportController" in ORTC; RtpTransport
// is to RtpTransportController as IceTransport is to IceTransportController.
