In the JDBC query result set, columns of type AggregateFunction cannot be parsed normally

## Description

When creating a materialized view, specify the Select statement as follows:

```sql
SELECT
toDate(timestamp) AS date,
countState(*) AS count,
quantileState(0.9)(duration) AS tp90_duration_ms,
quantileState(0.99)(duration) AS tp99_duration_ms,
avgState(duration) AS avg_duration_ms,
maxState(duration) AS max_duration_ms,
minState(duration) AS min_duration_ms
FROM test.test_table_local
GROUP BY
date
```
This statement is queried directly with JDBC, and the final error is:
java.sql.SQLException: Failed to read value for column count

final debug result：

1. BinaryStreamReader.java -> readValue method

case AggregateFunction:
return (T)this.readBitmap(actualColumn);
2. readBitmap method
```java
private ClickHouseBitmap readBitmap(ClickHouseColumn column) throws IOException {
return ClickHouseBitmap.deserialize(this.input, ((ClickHouseColumn)column.getNestedColumns().get(0)).getDataType());
}
```
column.getNestedColumns() is empty

### Error Log or Exception StackTrace

```
This statement is queried directly with JDBC, and the final error is:
java.sql.SQLException: Failed to read value for column count
```

### Expected Behaviour

### Code Example

```java

```

### Configuration

#### Client Configuration
```java

```

#### Environment
* [ ] Cloud
* Client version: 0.9.4
* Language version: 1.8
* OS: mac

#### ClickHouse Server
* ClickHouse Server version: 25.5.1

Commencez par BinaryStreamReader.java, en particulier readValue et readBitmap, et reproduisez la requête de la vue matérialisée avec ClickHouse Java client 0.9.4 contre ClickHouse 25.5.1. Examinez pourquoi AggregateFunction n’a pas de colonnes imbriquées ; le travail est terminé lorsque JDBC peut lire les colonnes du résultat agrégé sans la SQLException.
