[Feature Request] Screen Orientation/Rotation

[RhanCandia]

What feature should be added to Suwayomi-JUI?

Render orientation/rotation. The ability to render a content on specified orientation/rotation regardless of the desktop’s actual display settings.

Why/Project's Benefit/Existing Problem

With the rise of portable computing devoces like Steam Deck, ROG Ally, etc. I thought it would be nice if the application can render in an orientation independent of the actual settings of the device. This will help with the consumption of media like manga, etc. So we can read in a portrait orientation for example.
