Bugfix and stability improvements

MediaRenderer.enable and MediaRenderer.disable return type void instead of Promise<void>

New API for to specify the audio and video codecs that can be used for calls:

• Client.limitAudioCodecs()
• Client.limitVideoCodecs().

New events EndpointEvents.MediaRendererDisabled and EndpointEvents.MediaRendererEnabled to handle remote video receive stop and start in the conference calls. Remote video receive can be stopped:

• manually by MediaRenderer.disable API
• automatically by the Voximplant Cloud if the Voximplant Cloud has detected a network issue on the client

MediaRendererDisablingReason enum provides the information about the reason why remote video receive is stopped.

Auto gain control, echo cancellation, and noise suppresion cannot be disabled via AudioDeviceManager.setCallAudioSettings or AudioDeviceManager.setDefaultAudioSettings().

If multiple calls are connected at the same and one of the call is ended, local video is no more sending in other active calls.

Viewers in mixed audio conferences cannot hear each other.

Call.sendVideo() rejects the promise if the API is called with non-boolean argument.
