Mysql Binlog数据同步基于 position 起始点不生效

### Search before asking

- [X] I had searched in the [issues](https://github.com/DTStack/chunjun/issues) and found no similar issues.

### What happened

当我想采用 binlog文件名 + 索引位 消费数据的数据，配置不生效，是我的配置有问题吗？目前官网文档不全
### 我的配置信息如下：

```json
{
"job": {
"content": [
{
"reader": {
"parameter": {
"schema": "test_data",
"ddlSkip": true,
"start": {
"journal-name":"mysql-bin.000013",
"position":61507
},
"column": [
{
"name": "address",
"type": "varchar"
},
{
"name": "age",
"type": "int"
},
{
"name": "email",
"type": "varchar"
},
{
"name": "id",
"type": "varchar"
},
{
"name": "id_card",
"type": "varchar"
},
{
"name": "name",
"type": "varchar"
},
{
"name": "sex",
"type": "varchar"
},
{
"name": "student",
"type": "varchar"
},
{
"name": "type",
"type": "char"
}
],
"pavingData": false,
"password": "123456",
"database": "test_data",
"splitUpdate": false,
"port": "3306",
"cat": "insert,update,delete",
"host": "10.0.103.252",
"jdbcUrl": "jdbc:mysql://10.0.103.252:3306/test_data?characterEncoding=utf8&useUnicode=true&useSSL=false",
"table": [
"test_data_min_100"
],
"username": "root"
},
"name": "binlogreader"
},
"writer": {
"parameter": {
"producerSettings": {
"retries": "3",
"request.timeout.ms": "60000",
"batch.size": "16384",
"acks": "0",
"bootstrap.servers": "hadoop1:9092,hadoop2:9092,hadoop3:9092",
"buffer.memory": "33554432"
},
"topic": "duan_100"
},
"name": "kafkawriter"
}
}
],
"setting": {
"speed": {
"bytes": 1024
}
}
}
}
```

> 可以确认的是，这个binlog文件和索引是真实存在的，我们看一条模拟数据：

```json
{
"message": {
"schema": "test_data",
"database": null,
"opTime": "1687140107000",
"before": {

},
"lsn": "mysql-bin.000013/000000000000061507",
"after": {
"id": "Nh9EunM7kt",
"name": "Rosa Morgan",
"age": "503",
"sex": "F",
"address": "582 Grape Street",
"email": "rosamo824@gmail.com",
"id_card": "KsGQDpNgxF",
"student": "qa99aoQt98",
"type": "T"
},
"type": "INSERT",
"table": "test_data_min_100",
"ts": 7076390319717224464
}
}
```

`"lsn": "mysql-bin.000013/000000000000061507",` 这个信息应该记录的是该数据所在binlog文件的具体位置，现在想实现的功能是，从当前这个数据作为起始点，向下消费！目前配置不生效

### What you expected to happen

## 期望可以根据
```txt
journal-name：文件名，采集起点从指定文件的起始处消费；
position：文件的指定位置，采集起点从指定文件的指定位置处消费
```
进行消费数据！

### How to reproduce

json文件如下：
```json
{
"job": {
"content": [
{
"reader": {
"parameter": {
"schema": "test_data",
"ddlSkip": true,
"start": {
"journal-name":"mysql-bin.000013",
"position":61507
},
"column": [
{
"name": "address",
"type": "varchar"
},
{
"name": "age",
"type": "int"
},
{
"name": "email",
"type": "varchar"
},
{
"name": "id",
"type": "varchar"
},
{
"name": "id_card",
"type": "varchar"
},
{
"name": "name",
"type": "varchar"
},
{
"name": "sex",
"type": "varchar"
},
{
"name": "student",
"type": "varchar"
},
{
"name": "type",
"type": "char"
}
