[Feature Request] Multi-user support

[maximxlss]

Currently, there is no easy way to control which apps would be visible (technically installed) in the additional accounts. pm allows to do that easily, with pm install-existing --user <uid> and pm uninstall --user <uid> . I propose adding an option to do just that to sidequest.

Why is it important:

• When you add an account, no apps show up. You have to reinstall everything to make them show up.
• Patching Beat Saber works only when it exists on one account only. By uninstalling it on the other accounts you can get BMBF to install and then, after "reinstalling" it for the other accounts have it work properly.

Notes:

• If you pm uninstall --user <uid> a package for all users, it would break (maybe intended, didn't do research) and you won't be able to pm install-existing --user <uid> it back
• Here's my tool for that _{which I overengineered terribly, but hey, I had fun}

Details:

• I imagine adding a window, which opens up when trying to unistall an app if you have multiple accounts, which would have switches for every user on the device, not allowing the amount of users with the app to drop below one (disable the switch) + a button "uninstall"
