* Adds support for multiple layouts. Adds custom keymap for "offset"
layout.

* Adds a tool to help detach the keyboard from the Linux HID driver before programming.

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.

# JJ40 Tools
## usb_detach.c
When trying to flash on Linux, you may encounter a "Resource Unavailable" error. This means that Linux's HID driver has taken exclusive control of the keyboard, and the program script can't flash it.
This program can force Linux to give up a device, so that the programming script can reset it.
### To compile:
```
gcc usb_detach.c -o usb_detach
```
### To run:
1. Use `lsusb` to discover the Bus and Device numbers for your keyboard.
2. Run the program: `sudo ./usb_detach /dev/bus/usb/<BUS>/<DEVICE>`.
3. Build and program the firmware as normal.
