RTCIceCandidatePairStats: currentRoundTripTime property

A floating-point value indicating the round-trip time, in seconds for the connection described by the pair of candidates for which this RTCIceCandidatePairStats object offers statistics.

This value is computed by observing the time that elapsed between the most recent STUN request being sent to the remote peer and the response to that request arriving. This information may come from ongoing STUN connectivity checks as well as from consent requests made when the connection was initially being opened.
