listAllObjectsV2 method internally uses listObjects instead of listObjectsV2

[tomekit]

I am not exactly sure if that's intended, but I believe this is some sort of mistake.

Basically, the listAllObjectsV2 method name as well its description: "...This uses ListObjectsV2 in the S3 API..." implies that it's using the V2 API, but in fact it's using the old ListObjects internally.
I was also confused what's actually the difference between: listAllObjectsV2 and listObjectsV2, if both by default return all objects (they paginate over the results).

I am not complaining, don't get me wrong, this project is amazing and way more powerful then the AWS Amplify for Flutter.
It's just I've thought I will highlight some inconsistencies.

Thanks
