Using the IZoomSDKRenderer* videoHelper to record multiple participants

@gofmannir,

1. Please make sure both users are sending / starting their video, before the Linux “bot” can receive their video.
2. You can receive up to 4 * 360p video per instance of SDK. If you need more than 4, the strategy is either

• subscribe to a lower resolution, so you can get 17 * 180p
• or spin up another Linux "bot to subscribe to additional users at 360p
