Added support for queries that return scalar results (#11)

* Added support for queries that return scalar results

A scalar result is returned as:

```
[
    {
        "status": "Success",
        "kind": "upsolver_scalar_query_response",
        "result":
        {
            "scalar":
            {
                "value": "<value_here>",
                "valueType": "<value_type_here>"
            }
        }
    }
]
```

This commit transforms this result into a 1x1 grid with a column name of
`valueType`.

* v0.1.8
