Example usage:

*Adding a third party ad server id to an existing YouTube video*:

```ruby
content_owner = Yt::ContentOwner.new refresh_token: '...'
video_id = 'video_id'
third_party_video_id = 'third_party_video_id'

yt_video = Yt::Video.new(id: video_id, auth: content_owner)
new_ad_formats = Set.new(yt_video.ad_formats).add('third_party').to_a
yt_video.advertising_options_set.update(ad_formats: new_ad_formats, tp_ad_server_video_id: third_party_video_id)
```
