getRemoteCertificates
Returns the certificate chain in use by the remote side, with each certificate
encoded in binary Distinguished Encoding Rules (DER) [X690].
getRemoteCertificates() will return an empty list prior to selection of the
remote certificate, which will be completed by the time RTCDtlsTransportState
transitions to "connected".
