Calendar & Archives widgets

First of all, thanks for the plugin!

For the widgets endpoint, I noticed that you have built some logic for specific widgets like categories and recent widgets.

Others only get default values like type/instance/value. So for widgets like archives, search and calendar we get an empty array as a value.

I wonder if you have any plans on rolling out any of these widgets. If not, I’d like to know if you have any guidelines or tips on how one can contribute.

Cheers!
