Noticed that signatures [...] not being redacted. [...]

Description

Allow users to remove signatures from documents:

• all signatures on saving
• single signatures, e.g., with right-click context menu

Implementation

• Backend: PyMuPDF knows widget types and one is PDF_WIDGET_TYPE_SIGNATURE, thus, they may be removed with page.delete_widget(widget).
• Frontend: As additional dialog during saving? Or an advanced saving option? Or extra buttons for removing signatures?
