immersive mode to hide status bar

[martindmtrv]

Hey thanks for making this repo!

I just wanted to add another tip I found when setting up. You can actually fully remove the status bar using adb as well to hide that "my mini read" from the top corner of the screen. Also most ereader apps already come with their own status and clock info which is more useful to me

You also don't lose the quick settings it is still a single swipe from the top!

To remove the status bar:

adb shell settings put global policy_control immersive.status=*

To revert this change:

adb shell settings put global policy_control null*
