@uppy/aws-s3: issue tracker

[qxprakash]

As the rewrite of @uppy/aws-s3 is nearing it's completion I thought it would be best to have all the issues tracked in one place which this rewrite aims to close

I wrote regression tests ( leveraged AI heavily ) for all the issues which were reproducible and manually tested most of them against a real S3 bucket, few issues which were not entirely dependent on @uppy/aws-s3 client plugin were left out. There were total 18 open issues tagged with "AWS S3"
