the bug phenomenon：
use query-execution page to query table and this table include decimal type column，but the ckman display ”Decimal128 is not supported “
solution：
I find clickhosue-go already fixed this bug，refer to ：ClickHouse/clickhouse-go#401
First I upgraded ckman‘s clickhouse-go dependence from v1.4.5 to v1.4.6
The ckman no longer display “Decimal128 is not supported”,but decimal type column became garbled，then I test clickhouse-server.go's QueryInfo function ,the problem was located.
when Clickhouse column is decimal type, it returns 16 length byte array ，so I fixed this bug refer to clickhouse-go V2 Code.
