Feature request - Apply config/preset non interactively

[ABelliqueux]

If I'm not mistaken, right now, to apply a config or preset file you have to launch with -a or -c flag, but you still have to type q after that to quit the TUI.

It would be nice to be able to apply a preset/config and quit instantly/not launch the TUI at all, using for example a -q/--quiet flag, e.g:

# Load config and apply it without launching TUI 
camera-ctl -c /path/to/conf.file -q
# Load preset 5 from /path/to/presets and apply it without launching TUI 
camera-ctl -p /path/to/presets -5 -q
