全量传输时，遇到带有bit类型的表，job出现dead状态

[AstonPudding]

Description

在使用dtle从MySQL到MySQL的单库全量传输数据时，遇到表中带有bit类型的字段时会在日志中输出mysql.extractor. error，导致job为dead状态。

Steps to reproduce the issue

1. job.json

{
	"Name":"src_to_dest",
	"Tasks":[
		{
			"Type":"Src",
			"Config":{
				"Gtid":"",
				"ReplicateDoDb":[
					{
						"TableSchema":"mcc",
						"Tables":[
						]
					}
				],
				"ConnectionConfig":{
					"Host":"192.168.86.101",
					"Port":"3306",
					"User":"dba",
					"Password":"123456",
					"Charset":"utf8mb4"
				}
			}
		},
		{
			"Type":"Dest",
			"Config":{
				"ConnectionConfig":{
					"Host":"192.168.86.102",
					"Port":"3307",
					"User":"dba",
					"Password":"123456",
					"Charset":"utf8mb4"
				}
			}
		}
	]
}

2.表结构

CREATE TABLE `app_a` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT ,
  `p_id` int(11) NOT NULL COMMENT ,
  `p_name` varchar(20) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL ,
  `s_name` varchar(20) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL ,
  `s_identify` varchar(20) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL ,
  `is_enabled` bit(1) NOT NULL DEFAULT b'0' ,
  `update_by` varchar(64) CHARACTER SET utf8 COLLATE utf8_unicode_ci DEFAULT NULL ,
  `update_time` datetime DEFAULT NULL ,
  `create_by` varchar(64) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL ,
  `create_time` datetime NOT NULL ,
  PRIMARY KEY (`id`),
  UNIQUE KEY `uniq_index_scene_identify` (`s_identify`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC

3. 创建任务后，发现日志中有如下错误信息

Describe the results you received

src实例中已经不存在binlog dump线程，且job状态为dead

shell > dtle job-status
ID                                    Type         Status
55af1e10-5ab1-fc61-8795-cc530128bb41  synchronous  dead

Describe the results you expected

job启动后能够正常传输带有bit类型的数据

Output of ./dtle version:**

Dtle 2.19.11.0 (git: 2.19.11.0 292c35814fac4e213524446cd8285968087eb098)

Additional information

曾尝试过将bit类型的字段删掉或修改为int类型可以正常传输，只有为bit时会导致job死亡。
