syncTagsWithType method is inconsistent with laravel sync method

[AidasK]

syncTagsWithType return is void, though native laravel sync returns array of changes.

    public function sync($ids, $detaching = true)
    {
        $changes = [
            'attached' => [], 'detached' => [], 'updated' => [],
        ];
        ....
        return $changes;
    }

I think same return could be implemented for this package as well as it would be super helpful in some situations and would require less queries to do that.
