Would you add a small code snippet to show how to turn it on? I assume the default is OFF.

- Improved handling of closed sessions and operations (databricks/databricks-sql-nodejs#129).
Now, when session gets closed, all operations associated with it are immediately closed.
Similarly, if client gets closed - all associated sessions (and their operations) are closed as well.

**Notes**:

Cloud Fetch is disabled by default. To use it, pass `useCloudFetch: true`
to `IDBSQLSession.executeStatement()`. For example:

```ts
// obtain session object as usual
const operation = session.executeStatement(query, {
runAsync: true,
useCloudFetch: true,
});
```

Note that Cloud Fetch is effectively enabled only for really large datasets, so if
the query returns only few thousands records, Cloud Fetch won't be enabled no matter
what `useCloudFetch` setting is. Also gentle reminder that for large datasets
it's better to use `fetchChunk` instead of `fetchAll` to avoid OOM errors:

```ts
do {
const chunk = await operation.fetchChunk({ maxRows: 100000 });
// process chunk here
} while (await operation.hasMoreRows());
```

## 1.3.0

- Implemented automatic retry for some HTTP errors (429, 503) (databricks/databricks-sql-nodejs#127)
