Issue with syncTagIds and laravel-pivot-events package

[scramatte]

Hello,

I'm using your package and I need to detect changes that occurs with tags.
For that I'm using https://github.com/mikebronner/laravel-pivot-events package and it works very well.

When I delete tags , the "pivotDetached" is fired and I'm able to detect which tags have been removed.

The problem is when you attach tags. The "pivotAttached" event is fire for each added tag.
It occurs because in "HasTags" trait into "syncTagIds" method you make a loop to add tag one by one.

Into the following code , it will necessary to remove loop.

if (count($attach) > 0) {
            collect($attach)->each(function ($id) {
                $this->tags()->attach($id, []);
            });
            $isUpdated = true;
}
