Supress initial display when creating a tqdm notebook widget

[elvinlemmens]

I was wondering if it would be possible to have an option to disable the initial display action when creating a tqdm notebook widget, so that one could place the widget where it would be needed instead of always displaying it.

I don't think it is in fact a duplicate of the issue you posted. I think it due to the display(container) in tqdm.notebook.py. If you make this optional, one could manually display the widget where one would need it by using the container parameter to add it to a parent widget.
