Return the field value from map/struct, interface{}.
// map
cvt.FieldE(map[int]interface{}{123: "112233"}, "123") // "112233"
cvt.FieldE(map[string]interface{}{"123": "112233"}, "123") // "112233"
// struct
cvt.FieldE(struct{
A string
B int
}{"Hello", 18}, "A") // "Hello"
cvt.FieldE(struct{
A string
B int
}{"Hello", 18}, "B") // 18
