Add a function to normalize font size and checkbox style

[nonprofittechy]

We have some AssemblyLine conventions about font size, field properties and checkbox style. E.g., no scrollable text, use multi-line text for area fields, use font size 10, use the X style checkbox. Currently, automators who want to follow those conventions need to do it manually. It would be great to have some of this handleable by checking a single box "normalize fonts and styles" that would invoke a function in this package.

I'm hoping this is accessible with functions in PikePDF already.
