Add Secure PDF Generation Options to Prevent Editing Generated Doc

Anyone with Acrobat Pro can edit a Drawloop generated PDF document. This makes functionality, especially adding a watermark, relatively ineffective since it can be removed easily. We can ask our users to add a password but this leaves us exposed to manual error, the cost of Acrobat Pro licenses, and a much worse user experience.

It would be great to be able to add a password at the package level to prevent editing and secure documents. Ideally we would have the option to give end users the password via the interface or not. This would go a long way in keeping our IP private.
