Export Jupyter Widget as picture

[ccarli]

Feature Request

A perspective-widget python method to save the widget as a picture (something like widget.to_picture(path.png))

Use-case:

In my organisation we use jupyter notebooks in jupyterlab environment to automate tasks and reports, often sending automated emails to colleagues and management with latest available data in table / charts. I am using today persepective widgets in my python notebooks to explore and data because it's great and simple to use, but need to default back to matplotlib and styled dataframes when I want to send tables and charts in email. I would be great if perspective offers a way to save the widgets as a picture for straightforward integration in emails.
