EXPLAIN queries do not return results

[Sets88]

When running an explain query, such as:
EXPLAIN SELECT 1;

The fetch operation returns empty, so there is no way to obtain a result from this query.

Its looks like separate method .explain() which return string with response from ClickHouse.
@maximdanilchenko what do you think about this? I can implement it

In fact, after executing the 'explain' query, data is arriving in accordance with the sniffed network traffic. However, it is not being processed by the library. Therefore, if i was you I would not to create a separate method, but to process the received data in the normal way
