* Delete files by a custom callback function
*
* For example, do a database lookup on the order ID stored within the filename to ensure the order has been completed, if so delete the file.
*
* Callback function must accept one parameter (DirectoryIterator $file) and must return true (delete file) or false (do not delete file)
*
* Example to delete all files over 5Mb in size:
* $callback = function(DirectoryIterator $file) {
* if ($file->getSize() > 5 * 1024 * 1024) {
* return true;
* } else {
* return false;
* }
* }
*
* @param callable $callback
* @return array Array of deleted files
* @throws FilenameFormatException
* @throws RotateException
