Exception when inserting into a Dynamic type

[benedetto73]

Describe the bug I get this error when trying to insert data into a a table with a dynamic type. Actually a map with Dynamic values. Insertions without dynamic types work fine.

Schema of the table:

#	ColumnName	DataType
1	EventReceivedTime	DateTime64(3)
2	Name	LowCardinality(String)
3	Type	LowCardinality(String)
4	data	Map(LowCardinality(String), Dynamic)

Error I get:

Traceback (most recent call last):
  File "C:\Users\bened\AppData\Local\Programs\Python\Python311\Lib\site-packages\clickhouse_driver\columns\service.py", line 139, in get_column_by_spec
    cls = column_by_type[spec]
          ~~~~~~~~~~~~~~^^^^^^
KeyError: 'Dynamic'

To Reproduce

        record = (
                EventReceivedTime,
                Name,
                Type
                ,
                json.dumps({
                    'clientID': clientID,
                    'message' : message
                })
         )
        records.append(record)
            
        query = f'INSERT INTO {table_name} (EventReceivedTime,Name,Type,data) VALUES'
        client.execute(query, records)

Expected behavior I would expect the code to work unless Dynamc types aren't explicitly supported.
