Add A "Curly" Hair Texture Filter!

At the moment, the three hair textures we can filter by are Straight, Wavy, and Afro-Textured. As the game's catalog has grown and diversified, there is a substantial number of hair options that are decidedly curly – not wavy, but not afro-textured either. At the moment, curly hairs are awkwardly, and seemingly arbitrarily, placed into either the wavy or afro-textured categories; an example of this is the Curly Shag hair (pictured below) from the Anniversary Update, which was in the Afro-Textured category until the Sims team switched it to the Wavy category in the August 19 game update. Making a Curly filter will help with cleaner categorization for the range of hair textures we now see in The Sims 4.
