StandardFirmataBLE test for RedBearLab BLE Nano

/*
 * NOTE: This will not run without modification until this issue is resolved:
 * https://github.com/RedBearLab/nRF51822-Arduino/pull/97.
 *
 * Until then, you will need to patch the RedBearLab nRF51822-Arduino core
 * library by following these instructions:
 * 1. Install v1.0.7 of the RedBear nRF51822 Boards package using the Arduino
 *    Boards Manager (Tools > Boards > Boards Manager...). If you have a newer
 *    version already installed, first downgrade to v1.0.7.
 * 2. Clone https://github.com/soundanalogous/nRF51822-Arduino and checkout the
 *    stream-fix branch.
 * 3. From the cloned repo, copy the contents of the RBL_nRF51822 directory to
 *    the /1.0.7/ directory in the /RedBear/hardware/nRF51822/ package that was
 *    installed via the Arduino Board Manager. On OS X this is located in:
 *    ~/Library/Arduino15/packages/
 * 4. Copy StandardFirmataBLE and uncomment the 5 line #ifdef BLE_NANO block in
 *    bleConfig.h (File > Examples > Firmata > StandardFirmataBLE)
 * 5. Compile and upload your copy of StandardFirmataBLE to the BLE Nano
 *
 * To run with logging run as:
 * DEBUG=ble-serial node ble-nano-test
 *
 * To run, install the following modules:
 * npm install ble-serial
 * npm install firmata
