Problem with uppercase s3 bucket names

[mderazon]

Very useful tool, thanks for this.

I have a bucket that was named with Uppercase when it was still allowed. For example, MyBucket.

When trying to copy to the new account : MyBucket --> my-bucket it throws an error:

ERROR: bucket(mybucket) not found

(Ignoring the casing)

For now, I have copied MyBucket to another bucket with lowercase in the same account and then used the tool to copy between accounts.
