Cannot get Object from S3 bucket

This seems to happen _very_ intermittently.

When the adapter attempts to fetch an object from S3, S3 will produce an error, causing the adapter to throw and eventually bubble up to the hyper consumer.

I think we can add some resiliency here. Some potential strategies:

- If `getObject` fails, then retry up to 3 times with a backoff between retries
- Cache the result of `getObject` in memory. One of:
- fallback to cache, if `getObject` fails
- stale-while-revalidate pattern (using `setTimeout`)
