feat: Keep Video Brightness The Same After Closing The App And Then Re-Opening The App

[sliceanddice9]

Feature description

Have the video brightness of ALL VIDEOS you watch via the brightness swipe control gesture remain locked in place for when you close the app and reopen the app.

Right now if you set the brightness for a video you watch via the swipe control gesture to for example: 75 and then force close ReVanced - after you re-open ReVanced the video brightness defaults to 0. I want the video brightness to remain at 75.

Motivation

The original Vanced & Revanced Extended both allowed you to keep the video brightness via the brightness swipe control gesture in tact to whatever level you wanted it at, even after closing the app and then re-opening the app. ReVanced needs this same functionality.
