Add example with a custom carousel widget for rust, cpp and js

Looks good.

Maybe we should have a folder common to more demo to store the fonts?

Since there is no logic to this example, i wonder if it is a good idea to have a rust/cpp/node code, while just the .slint would suffice. On the other hand, it doesn't hurt to have it.

If you want the wasm demo to be compiled and uploaded, then you should also edit the .github/workflows/wasm_demo.yaml
I'm not sure we should do that since it has no UI. There can still be a demo using the previewer. (Same as the iot-dashboard)

We can think about that. Also if we start using the same fonts and icons in the same example.

I used this setup that you are able to run the carousel example also like this others described in the readme. And it can be used as based for someone new to Slint.

For completeness I add it to the yaml file. But if wanted I can remove it.
