/**
 * 响应用户的操作，不需要组件传递参数，这些操作对应的方法有：
 *
1. 增加KV
2. 减少KV
3. 增加MAS
4. 减少MAS
5. 增加MA
6. 减少MA
7. 增加MS
8. 减少MS
9. 增加Density
10. 减少Density
11. 增加Thickness
12. 减少Thickness
13. 设置APR
 * 以上方法内部逻辑是向服务发送设置曝光参数，KV MA MS MAS；间接调用api method，通过 调用 @/src/API/exam/APRActions.ts  中定义的方法完成调用，并不直接调用api
 * 接收device mqtt发来的新参数。device mqtt会触发事件 emitter.emit('NEW_KV',parsedMessage.CONTEXT); 这是接收KV新值的，还有对应的其他新曝光参数的新值
 * 把 device mqtt 发来的新参数传递给 @/src/states/exam/aprSlice.ts  。 dispatch thunk的 action，有fullfilled pending rejected ，比如 incMS.fulfilled ；考虑 device mqtt 发来新曝光参数会超时，超时的情况下向 aprSLice发送 rejected 。
