MechMerlin e16b39f0c2 Keyboard: Duck Jetfire QMK Support (#3752)
* Initial Commit

Port from xauser's jetfire code. Does not compile yet

* fix up keymap from uint8 to uin16

* update rules file to contain custom matrix

* Good stopping point

Still lots of compile errors but I'm getting there.

* fix a few more compile errors

* move a few functions around to help with compiling

* Finally got it all to compile

* Get rid of that old KEYMAP macro

* edit readme

* Put my name everywhere and some minor code clean ups

* start to remove that kc nonsense

* fix keymap compilation issues

* add reset key info

* better human readable formatting

* match the duck default layout

* add confgurator support

* clarify reset key

* might be a good idea to use the correct pin

* get the riight keycode for RGB

* include an ALL layout

* I tried to fix the formatting....sigh

* add functons to ensure Configurator compile-ability

* move jetfire to duck directory

* Moved and renamed things as per Drashna's PR comments as his back was hurting as he reviewed this
