Unsupported data type: BFloat16

[tolberg91]

Hi

I created a table with a column of type BFloat16 ( https://clickhouse.com/docs/ru/sql-reference/data-types/float ). And now I am trying to read this table with jdbc driver (version 0.8.5, https://mvnrepository.com/artifact/com.clickhouse/clickhouse-jdbc/0.8.5 ) but I am getting a error: Unsupported data type: BFloat16

Is there a reason, or is it an oversight?
