[wdkwyf]

Update UI and modify some demo logic including mstcn, skip frame.

@Wovchena sorry I forget to emphasize it's a draft pull request for now and thanks for your comments. I will fix them and let you know when it's ready ASAP.

[Wovchena]

Just not to forget. Please update model description and add new models to https://github.com/openvinotoolkit/open_model_zoo/tree/master/models/intel

The demo fails for me:

maybe the models you used were old. I sent your the new models and command via email.
