CTkProgressBar with windows taskbar

[arne182]

It might be nice for the ProgressBar in Windows to be connected to the Windows Taskbar. Here is some code that would allow you to show the CTkProgressBar progress on the Windows Taskbar

Thanks for mentioning this, I think this would be more of a separate component. I will think about adding this somehow in the future.
