support for Text Form Fields and Checkboxes

[jonas-kupferschmid]

I saw that Text Form Fields and Checkboxes are not implemented. docx-form has those implemented and I was able to extend it so that one can find and edit TextFormFields and Checkboxes with bookmarks. But sadly that project is not being maintained anymore,
Will they be implemented here at some point?
I would love to help and code it myself but it seems quite complex and I'm having a hard time understanding all classes and functions here

I might be interested in folding support for form elements into python-docx. Just ran into that need today. I've not had a chance to study https://github.com/Southeastern-Louisiana-University/docx-form to weigh how hard integrating the two code bases would be.
