Raw buffer being spit to log

Calling uploadFileToBucket() generates a big buffer object in the log.

```
<Buffer 48 54 54 50 2f 31 2e 31 20 34 30 33 20 46...
```

The problem line looks like this.

```
console.log(data);
```

To fix it I changed it to:

```
console.log(data.toString('ascii'));
```
