Music smart filters - date added and last played album rules

Just love the smart filter facility, makes browsing my music collection with Yatse a delight. I always use Yatse to control Kodi because of this great feature which is far more flexible than what I can do with the music screens in Kodi.

Could rules for date added and last played be added for filtering albums. Simple support for greater than and less than would be enough.

Thanks so much for implementing this - Yatse is best!
