Helper to easily access some [aws-sdk-go](https://github.com/aws/aws-sdk-go)'s methods and lambda utilities like preparing an sns default message and unmarshal an image coming out from a stream like:

```
// UnmarshalDynamoEvent unmarshals a events.DynamoDBEventRecord into a given target.
// Out has to be a pointer.
func UnmarshalDynamoEvent(event events.DynamoDBEventRecord, out interface{}) error {

if reflect.DeepEqual(event, reflect.Zero(reflect.TypeOf(event)).Interface()) {
		return errors.Wrap(bindings.ErrInvalidParameter, "event")
	}
	if reflect.ValueOf(out).Kind() != reflect.Ptr {
		return errors.Wrap(bindings.ErrInvalidParameter, "out")
	}

img := event.Change.NewImage
	if len(img) == 0 {
		return errors.New("event's image is empty")
	}

m := make(map[string]*dynamodb.AttributeValue, len(img))

for k, v := range img {

b, err := v.MarshalJSON()
		if err != nil {
			return errors.Wrap(err, "unable to marshal current element to json")
		}

var attr dynamodb.AttributeValue

err = json.Unmarshal(b, &attr)
		if err != nil {
			return errors.Wrap(err, "unable to unmarshal current element to json")
		}

m[k] = &attr

}

return dynamodbattribute.UnmarshalMap(m, out)

}
```
