Add basic Pybadge board definition

Currently boots on board and can connect to REPL,
but does not appear as mountable drive in OS.
Starting REPL gives the following error message:

```
You are running in safe mode which means something unanticipated happened.
Looks like our core CircuitPython code crashed hard. Whoops!
Please file an issue at https://github.com/adafruit/circuitpython/issues
 with the contents of your CIRCUITPY drive and this message:
Crash into the HardFault_Handler.
```
