Added new UI for the Temporal Sync Feature, made the software more robust including:

-Settings window can only be opened once
    -When the client can't open a device, it tries multiple times
    -Recording bins are now saved with a unique ID per device, to allow multiple clients to record on the same PC
    -Synchronized & Unsynchronized devices can be both used in one server
    -Included a workaround for a bug in the Azure Kinect SDK regarding exposure (microsoft/Azure-Kinect-Sensor-SDK#1378)
