Fixed No clean way to manipulate the AttachmentData entity before the file is copied

Affected version
2.1.7

I'm making some changes to how attachments are stored for certain cases, but am not able to manipulate anything within the AttachmentData entity before it's saved, and the files have already been uploaded within \XF\Service\Attachment\Preparer::insertDataFromFile so I'm required to overwrite the entire method which doesn't seem very clean, and prone to issues if this method gets changed. What I propose is the following:

Remove the following from insertDataFromFile

PHP:
/** @var \XF\Entity\AttachmentData $data */
$data = $this->app->em()->create('XF:AttachmentData');
$data->user_id = $userId;
$data->set('filename', $file->getFileName(), ['forceConstraint' => true]);
$data->file_size = $file->getFileSize();
$data->file_hash = md5_file($sourceFile);
$data->file_path = $extra['file_path'];
$data->width = $width;
$data->height = $height;

if ($extra['upload_date'])
{
   $data->upload_date = $extra['upload_date'];
}

if (!$data->preSave())
{
   throw new \XF\PrintableException($data->getErrors());
}

and place it into a separate function:

PHP:
protected function initializeAttachmentDataFromFile(\XF\FileWrapper $file, $userId, array $extra = [])
   {
       $sourceFile = $file->getFilePath();
       $width = $file->getImageWidth();
       $height = $file->getImageHeight();
       
       /** @var \XF\Entity\AttachmentData $data */
       $data = $this->app->em()->create('XF:AttachmentData');
       $data->user_id = $userId;
       $data->set('filename', $file->getFileName(), ['forceConstraint' => true]);
       $data->file_size = $file->getFileSize();
       $data->file_hash = md5_file($sourceFile);
       $data->file_path = $extra['file_path'];
       $data->width = $width;
       $data->height = $height;

       if ($extra['upload_date'])
       {
           $data->upload_date = $extra['upload_date'];
       }

       if (!$data->preSave())
       {
           throw new \XF\PrintableException($data->getErrors());
       }
       
       return $data;
   }
