  clientSecret - {string} AVS client secret found in portal. Only needed if using `code` response type.
  deviceId - {string} AVS device Id found in portal
  deviceSerialNumber - {number} serial number for this device (can be made up)
  redirectUri - {string} redirect uri set in portal

avs.login({responseType: 'code, token (default)', newWindow: false}) -> promise(response);
avs.promptUserLogin() -> alias to login();
avs.logout() -> promise();
avs.getTokenFromUrl() -> promise(token);
avs.getCodeFromUrl() -> promise(code);
avs.getTokenFromCode(code) -> promise(response);
avs.getTokenFromRefreshToken(refreshToken) -> promise(token)
avs.refreshToken() -> promise({token, refreshToken})
avs.getToken() -> promise(token)
avs.getRefreshToken() -> promise(refreshToken)
avs.requestMic() -> promise(stream);
avs.connectMediaStream(stream) -> promise;
avs.stopRecording() -> promise;
avs.startRecording() -> promise;
avs.sendAudio(dataView) -> promise(response); - send audio to AVS and get back an object containing response.
The response object is the parsed http message.
avs.audioToBlob(AudioBuffer | DataView) -> promise(blob) - mp3 blob
