Instagram Video Controls

Adds Instagram video controls that actually work, unlike the other extensions that are presently on the web store Please consider tipping me via https://streamlabs.com/nostril_dumbass/tip. Any tips are appreciated! 1.3: Attempted fix for random extra control bars that would render for a video that isn't visible on the page (some were ads that may be blocked by other extensions). Added sublte outline to Play/Pause button. Per report/recommendation of first user review. Thank you Gregorio! 1.2: Instagram keeps making updates that seem to intentionally break custom extensions like this. It's beyond me why they care that people can seek/adjust volume on videos. I got this working again from my end. 1.1: Added fix to enable the video player controls to all videos as opposed to only the first one on the page
