Make getDocumentCameraViewController() as public extension

[iTarek]

Hello,

I do not want to use IRLPDFScanContent.present to display the DocumentCameraView. Instead, I want to use SwiftUI's .fullScreenCover. Therefore, I need the ViewController. I noticed that getDocumentCameraViewController() is not public. If you could make it public, it would be very helpful.

Thank you.
