Fix ClickHouse test import to match new JDBC driver package layout

ClickHouseBinaryComparisonOperationTest still imported
com.clickhouse.client.ClickHouseDataType. In ClickHouse JDBC driver
0.9.6 (commit 918e513, "Upgrade ClickHouse JDBC driver from 0.3.2
to 0.9.6") that class was moved to the com.clickhouse.data package
along with all the production-side usages, but the test file was
missed. Production code already imports it from the new package, so
this aligns the test with the rest of the codebase.

Without this fix every CI job on PR #5 fails at testCompile with
"The import com.clickhouse.client.ClickHouseDataType cannot be
resolved", e.g.:
