Add flipbook animation (#246)

Add a new `Attribute::SPRITE_INDEX` and a new `FlipbookModifier` to
enable spritesheet-based "flipbook" animation of particles.
- The texture from a `ParticleTextureModifier` is sliced into a grid as
  specified by the `FlipbookModifier`;
- Each frame, the renderer reads the `Attribute::SRITE_INDEX` of the
  particle and selects the Nth sprite in the spritesheet.

There is currently no built-in animation of `Attribute::SPRITE_INDEX`;
instead you should use the Expression API to update the attribute each
frame. This allows total control on the animation speed / framerate, any
looping, or even allows non-linear framerate and complex indexing into
the spritesheet.

Fixes #108
