[Feature] Nordic Keyboard support

[MagicBOTAlex]

Hey, I only use Nordic keyboard layout, and I'm wondering if this would be something that would be possible to add.

Nordic keyboards are used in:

• [x] Denmark (Me)
• [ ] Norway
• [ ] Sweeden

As far as I know, so it would be great having support for the nordic layout.

Also, I have contributed to other open-source projects before, but they usually have a contributing section in the readme. So is contribution possible/allowed? It's also a way for me to support the project.
