Could we save the depth map image at the same time?

Hi, team, thanks for your effort in this project.

I am using 2 Azure Kinects and I wonder if I could save the depth map image at the same time. Since right now we can only save .ply file, so we wanna save the depth image (like "show depth" in the LiveScanClient) simultaneously.

Or did you leave any API that I can leverage to extend the function?
