Parses timestamps from the backend ( that arrives as a float64 ) using the [@google-cloud/precise-date](https://www.npmjs.com/package/@google-cloud/precise-date) lib to support microsecond resolution.

Example output:
```
const bigquery = new BigQuery();
const [rows] = await bigquery.query({
  query: 'SELECT TIMESTAMP("2014-09-27 12:30:00.123456Z")',
});
console.log(JSON.stringify(rows));
// [{"f0_":{"value":"2014-09-27T12:30:00.123456000Z"}}]
```

Fixes #6

`Query.wrapIntegers` was being ignored and not passed to `job.getQueryResults` when used in `bigquery.query`.

We use a common triage across the BQ SDK team, and auto-assigning to a specific user conflicts with that.  Removes blunderbuss rules forcing issues to be assigned to a specific contributor.
