Suggestion: Option to disable all animations

[Rolf-Smit]

Some composables in this project allow modifying the AnimationSpec, so I can effectively disable animations by passing a spec that has a hard-coded duration of 0.

However not all animations are modifiable in this way, for example the PieChart allows changing the animation of the pie itself, but not the animation of the labels.

I require the animations to be disabled in some scenario's, one of which is mostly to make previewing composables easier (right now they often don't display because of the animation).
