Backlight and RGB now working for JJ50 (#2929)

* Added support for JJ50 from KPRepublic, no rgb or backlight control yet. Added as a layout of ymd96 at the moment (same microprocessor). Basic keymap with three layers to get started. * Added support for JJ50 * Tidied up jj50 code, backlight and RGB is now working. * Renaming "KEYMAP" to "LAYOUT" to adhere to the new QMK standards.

 1. Try plugging the board in while pressing `Backspace` (`Key below the top right key`). This will force it to boot only the bootloader without loading the firmware. Once this is done, just reflash the board with the original firmware.
 2. Sometimes USB hubs can act weird, so try connecting the board directly to your computer or plugging/unplugging the USB hub.
 3. If you get an error such as "Resource Unavailable" when attemting to flash on Linux, you may want to compile and run `tools/usb_detach.c`. See `tools/README.md` for more info.
