Subfolders created outside asset volume not supported

[andrewmenich]

If a subfolder is created from the Asset tab, images uploaded to that subfolder will not get parsed correctly by the plugin. Currently the plugin builds the asset key using the volume URL (with subfolders) and the filename.

It seems that changing this line to "key" => $volumeSubfolder ? $volumeSubfolder . "/" . $image->getPath() : $image->getPath(), would do the trick.

Happy to submit a PR!
