Add user mode CLI command

[Dexter2038]

I needed it, so I added it.

Tested, everything is working.

Hey! Thanks for the PR, sorry it took me so long to come back to it, do you mind rebasing on the latest main? If you don't use this anymore tell me so I'll take care of it myself ;)

Thanks for getting back to me! I’m happy to rebase my branch since I’m still using my modified version of the app.

Changed some commits' names and authorship, fixed conflicts and fixed some errors. Pinned screenshot of successfully running program. It builds, it works. At least on my machine. Waiting to finally merge

Alright, just a tiny improvement and we're good

Added print on failed EC data update

Should I change "user mode" to "User Mode" for consistency? The code prints "Cooler Boost" and not "cooler boost", so I guess it would be better if naming would be the same, right?
