MySQL驱动包支持Boolean类型，canal不支持boolean类型转换

[kervin521]

MySQL的驱动包中对tinyint的长度为1，对应sqlType=-7,转化为Java布尔类型，参考MySQL驱动源码

而Canal对对tinyint的长度为1，对应sqlType=-6，无法处理为Java的布尔类型

没有专门针对tinyint(1)做过特殊处理，目前统一按照了tinyint类型-6

[kervin521]

有计划支持吗？

可以考虑提交一个PR给我

The fix still have some problem when sync data with tinyint(1) type. If not specify tinyInt1isBit in your jdbc url，the return java type is integer. Reference doc is https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-type-conversions.html
