Webtoon viewer landscape mode

Extension, that allows you rotate viewer, so it's easy to read landscape episodes on desktop

We love webtoons... Extension was created, because as primarly desktop user, reading webtoon episodes, that were made in landscape mode by author was annoying for one reason:

While it's easy to rotate your mobile device, it's not as easy to do with laptops or desktops (if you don't have Pivot monitor), that means if you opened episode that was made in landscape mode by author, text was rotated by 90° on screen, impossible to read it easily. And if you don't want to break your neck or rotate whole laptop (which is nonsense), it's better to have feature that allows you to rotate episode viewer, so landscape is readable on desktop.

For example second half of episode [SOULWINDER Ep. 39 - Forebode](https://www.webtoons.com/en/thriller/soulwinder/ep-39-forebode/viewer?title_no=2880&episode_no=39) has text rotated by 90° on desktop. This extension fixes the issue.

This extension add button to toolbar (that is at top of website in right corner), that allows you to switch to "landscape" mode (or back to standard mode).

Now we can easily read landscape episodes too. See screenshot of the episode above in landscape mode.
