support AZERTY layout

[thomasleveil]

Hi,

It would be nice if snaptile could support different keyboard layouts. Maybe python3-sdl2 can help, I found this example to detect keyboard layouts.

Would love it if someone can send a PR for this, I personally don't have a different keyboard layout to test with.
