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)

}

```
