support for iOS Home button in ble_hid_controls.js module

thanks to Raspberry PI Bluetooth implementation I was able to sniff around my Puck and another device that sends the Home button correctly :

bluetoothctl of my Puck

]);

NRF.setServices(undefined, {
 hid : report
});

NRF.on('connect', function(addr) {
  digitalPulse(LED3, 1, 1000);
});

NRF.on('disconnect', function(addr) {
  digitalWrite(LED3, 0);
});

function p(c,cb) {
  NRF.sendHIDReport(c, function() {
    setTimeout(function(){
      NRF.sendHIDReport([0,0], cb);
    },500);
  });
}

setWatch(function(){
  try{
    digitalPulse(LED1, 1, 50);
    p([0x23, 0x02],function(){print('done');});
  } catch (e) {
    print(e);
    digitalPulse(LED3, 1, [50,50,50,50,50]);
  }
}, BTN, {edge:"rising",repeat:true, debounce:50});

I tried with the ble_hid_controls.js module and it works on iPhone (almost same btmon trace but just 1 byte sent instead of 2).
