CSS in JS issues about fluent-ui-react

[layershifter]

After #1459 we will not need to switch renderers.
Fela is also compatible with TS --isolatedModules now 🚀

@levithomason FWIW, we're thinking about introducing dynamic direction support, adding the ability to switch rtl => ltr dynamically as well as having different modes for different sub trees :)

PS: I was thrilled to see Fela in the code here. Looks like a very promising UI library. If there's anything I can help with, feel free to hit me up =)

That would be awesome. This is one of the big hurdles for us now.

The other goal we have is to reduce the number of wrapping components around every UI component. This is the reason we are using the renderer directly opposed to an HOC.

3. Fela does not prefix keyframe class names - RTL keyframes rewrite LTR ones #516

4. Fela incompatible with --isolatedModules #613

Both the original issues are now solved 💪
