Unclosed resources?

[i124q2n8]

If you hash an image by filename the hash function will create a resource that is never closed.

https://github.com/jenssegers/php-imagehash/blob/master/src/ImageHash.php#L36

public function hash($resource)
{
    $resource = is_resource($resource) ? $resource : $this->loadImageResource($resource);
    $hash = $this->implementation->hash($resource);
    return $hash;
}

Resources should now be closed in the last commit :)
