Disney Plus Ultrawide Fullscreen Support

Toggle 21:9 Video on Disney Plus to be full screen on Ultrawide monitors (Removes Black Bars)

Adds a button to chrome toolbar to toggle fullscreen scaling of Disney plus video on Ultrawide Monitors which at the moment, is not supported. This is useful for 21:9 titles (most movies on disney plus), where letterboxing occurs, resulting in the titles no longer having the black bars on the side and top, allowing you to utilise the full size of your ultrawide monitor for a better viewing experience. Simply add the extension, and click the new button while viewing a disney plus movie to see the effect. Version 2.3 Fixed Missing Subtitle Bug
