feat: Add screenshot prevention for IOS

[JanStevens]

Hi,

It seems that this plugin overlaps with the existing community plugin: https://github.com/capacitor-community/privacy-screen/blob/main/ios/Plugin/PrivacyScreen.swift

The difference is that this plugin has better control on the blur effect while it is missing screenshot prevention on IOS.

Seems a good opportunity to merge in the community plugin screenshot prevention?

Regards,

[dvero23]

Any plans on when it will be added the feature?

Thanks

Hey there, thanks for opening the issue.

The team has backlog to address it, but I can't provide a timeline at this time, apologies.
