Add support for sensor_cube.aqgl01
I realised that MiAqaraPlatform was finding my cube but not recognising it as the magic cube:

```
[2018-6-6 16:08:48] [MiAqaraPlatform] [DEBUG][Send]{"cmd":"read", "sid":"158d000231e6d3"}
[2018-6-6 16:08:48] [MiAqaraPlatform] [DEBUG][Revc]{"cmd":"read_ack","model":"sensor_cube.aqgl01","sid":"158d000231e6d3","short_id":60961,"data":"{"voltage":2905}"}

```
Turns out that my cube is the model "sensor_cube.aqgl01" so I added it to "parser/MagicSquareParser.js" in the following line:

`MagicSquareParser.modelName = ['cube', 'sensor_cube', 'sensor_cube.aqgl01'];
`

Now it finds it, recognises it and configures it, great! :-), 

The problem now is that I don't receive any event message from the gateway, when I move the cube it appears in the log of the YiHome App but I receive nothing, what can I do? Can you help me @YinHangCode ?

Thanks!
