Add additional presets

Once issue #31 is finalized, it would be nice to add an initial layer of additional presets/variations using the architecture.

While there are unlimited tween behaviors one could think of, some common ones stand out at the top of the list:
(inspired by https://pub.dev/packages/animate_do and https://animate.style/)

```
FadeInUp
FadeInDown
FadeInLeft
FadeInRight

FadeOutUp
FadeOutDown
FadeOutLeft
FadeOutRight

SlideInUp
SlideInDown
SlideInLeft
SlideInRight

SlideOutUp
SlideOutDown
SlideOutLeft
SlideOutRight

FlipInX
FlipInY
FlipOutX
FlipOutY

ZoomIn
ZoomOut

BounceIn
BounceOut
```

Notably, some of these are simple variations of existing effects (`SlideDown` or `ZoomIn`), while others are composed of multiple effects (`FadeInDown`). Ideally the new system supports composition, so `FadeInDown` uses `FadeIn` + `SlideInDown` rather than re-creating their logic.

This issue could be thought of as a first pass at the most obvious presets, and then other presets could be considered in the future. Mostly this can serve as dogfood for issue #31
