[Feature request] Keyboard layout autodetection

[jruelle23]

I think it'd be nice to have, alongside this recently merged PR, an autodetection feature when the configuration for the keyboard is empty:

[keyboard]
# Keep unset for autodetection
# layout = ...

There are multiple ways of doing that detection, and the tricky part can be in which priority order we want them to occur, my first draft would be:

1. Checking the env var XKB_DEFAULT_LAYOUT (depends on the desktop env installed if there is one at all)
2. Checking with localectl status (systemd dependent)
3. Guessing with the env var LANG result
4. Fallback to "us" if none works or an unexpected error happens.

I don't know if there are better solutions and I hesitate between 1. and 2. for the priority order.

I like the idea, but an env var won't work when the server is launched through a systemd service because there's no env variables in that case (or likely not the one you need). Since moonshine already depends on systemd for launching applications, localectl seems like a nice solution.

Ok, I'll try to implement that then.

Hi, just so you know, since I'm a newbie on rust dev, I'm learning and refining my code on the way, so it may take a while.

No worries 👍
