  * Wrapper around an S3 object that will retry the {@link GetObjectRequest} if the download fails part-way through, resuming from where
  * the failure occurred. This should be handled by the SDK but it isn't today. This should be revisited in the future (e.g. before removing
  * the {@link Version#V_7_0_0} version constant) and removed when the SDK handles retries itself.
