feat: allow customizing the dlq name, add outputs (#61)

## Description
Allow specifying the name of the created dlq compared to using normal
queue name + "-dlq". Add outputs of the created sqs queues.

## Motivation and Context
We want to have a custom named sqs queue from which we can read using a
different consumer, as such the default -dlq ending would be misleading.
