Add camera animation capabilities (anime.js)

Interface for capturing, serializing, and replaying camera settings.
- [ ] manually capture keyframes with camera eye, center, fov
- [ ] automaticall capture keyframes ...
- [ ] specify replay by means of duration between frames, ease-in/ease-out functions, interpolation method, etc.
- [ ] passive replay by querying interpolated data for certain point in time or position in-between

As originally intended in [webgl-operate](https://github.com/cginternals/webgl-operate/issues/176) we could generalize this interface to a `DataCapture` and `DataReplay` class... but perhaps we could rely on [anime.js](https://animejs.com/) instead.
