Add missing `Hash` output format to `ClickHouseFormat` enum (JDBC/DataGrip throws "No enum constant ... Hash")

### Use case
Running a `SELECT ... FORMAT Hash` query through the JDBC driver (e.g. from DataGrip) fails with:

No enum constant com.clickhouse.data.ClickHouseFormat.Hash

The `Hash` output format (https://clickhouse.com/docs/interfaces/formats/Hash) is supported by the ClickHouse server but is not present in the`ClickHouseFormat` [enum](https://github.com/ClickHouse/clickhouse-java/blob/main/clickhouse-data/src/main/java/com/clickhouse/data/ClickHouseFormat.java), so the driver throws before the query is ever sent.

Start in clickhouse-data/src/main/java/com/clickhouse/data/ClickHouseFormat.java and inspect how output formats are represented and parsed. Reproduce the JDBC/DataGrip failure with a SELECT ... FORMAT Hash query, then verify that Hash is recognized without the No enum constant error and that the query can be sent to ClickHouse.
