Multiple layers of Lazy<T>ness are replaced with an explicit two-part loading scheme. Sequences are parsed immediately, without the need for the sprite assets, and tell the SpriteCache which frames they need. Use-cases that want the actual sprites can then tell the SpriteCache to load the frames and the sequences to resolve the sprites.
