add de104 keyboard layout

adds the german keyboard layout

[vinc]

Hello, I tested your layout in MOROS and every chars that my OS can print looks good, including ä, ö, and ü, but the < key at the bottom left of that image doesn't produce anything: https://en.wikipedia.org/wiki/File:KB_Germany.svg

I think the following PR had the same issue: #8

Does that key work for you @kevtechXx?

Nope it also doesn't work for me.
On german keyboards the < key returns keycode 0x56 which doesn't get decoded by both ScancodeSet1 and ScancodeSet2 :/

I believe the fix is to change

pc-keyboard/src/scancodes.rs

Line 159 in 50d9ced

//0x56

and emit a new enumerator called something like KeyCode::Oem102. You can then check for that keycode and emit <, > or | as appropriate.

The name OEM 102 was taken from https://kbdlayout.info/kbdgr/scancodes

Also, thank you for the PR!
