Composer conflicts

Hi,
I just tried your plugin, but the choose bucket modal was always empty. I figured out it’s because you have guzzlehttp 7.x installed while I was already using 6.x and they are not compatible. Please consider using https://github.com/typisttech/imposter-plugin to namespace your dependencies so they don’t interfere with others. Many other plugins use composer w/o namespacing unfortunately, so chances of conflicts are not negligible.

Also please consider an option to disable setting the ACL when uploading to S3. My buckets don’t need/use it, so I’d rather not turn it on to use the plugin.
