[FR] "Save" PDF capability to allow PDF Form workflows with PDF++

Problem

When filling or updating PDF Forms I need to reference or cite information in my Obsidian vault. But saving changes made to PDF Forms using using the PDF++ Obsidian plugin isn't possible.

This limitation is a gap in Obsidian-based PDF workflows.

• At worst, changes are lost if the limitation isn't known beforehand.
• At best, it forces PDF++/Obsidian users to split their digital form and CMS between seperate applications.

Proposed solution:

1. Open form-enabled PDF in Obsidian with PDF++ plugin AND 'PDF Save' enabled
2. Make changes content in form fields by updating their contents.
3. Click Save in PDF++ toolbar.
4. Form changes persist in the original PDF document.
