[REQUEST]: Label property for StreamReceiverBase

[kannan-xiao4]

Is your feature request related to a problem?

When receiving from multiple Peers, I would like to specify the target to be received for each StreamReceiverBase. Currently, it can be determined only by the connection ID, so I would like to be able to identify it by Label as well as Datachannel.

Describe the solution you'd like

Add label property to Stream component types using RTCRtpTransceiver.mid

Describe alternatives you've considered

No response

Additional context

I also want a sample of multiple receptions based on Broadcast
