Feature Request: Automatically Rotate to Landscape for Double Pages

Description:
Add an option in ComicReader to automatically rotate the display to landscape orientation when a double page is detected and shown. This will improve readability and provide a better experience when viewing wide comic spreads.

Details:

• Automatically detect when a double page is displayed (using the DoublePage attribute in ComicInfo.xml if available).
• Rotate the view to landscape mode for optimal presentation.
• There needs to be an option to enable/disable this feature.
