Product, Brand and Description missing

probably related to the changes here:
https://github.com/stampzilla/gozwave/blob/master/nodes/node.go#L192

My device looks like this. The name should default to brand - product
```
{
  "type": "lamp",
  "node": "9e774f59-d47d-4d40-9553-4b6248cdd768",
  "id": "1009",
  "name": " -  (Address: 1009)",
  "online": true,
  "state": {
    "on": null
  },
  "tags": null
}
```
