Re: [webrtc-pc] Order of RTCRtpSendParameters.encodings is not described

In the current specification, order matters in several aspects: 

1. When more simulcast layers are requested in `sendEncodings` than can be supported, layers are dropped "from the tail".

2.  `setParameters` does not currently permit reordering of `encodings`, so that ordering is fixed once `addTransceiver` is called.

My advice would be to indicate that no particular ordering is required, but to include a note in `setParameters` explaining the effect of ordering.
