Add animated dash line example

[ravenfeld]

Hello, I'd like to make a line with dash animations.

I found this issue on the old repo
mapbox/mapbox-android-demo#795

Do you know if this is feasible now?

Thanks in advance

Yes that should be possible by continuously updating the line-dasharray property: https://maplibre.org/maplibre-style-spec/layers/#line-dasharray

The jsbin you linked gives you an idea.

Ok, there's nothing that's currently done. It's up to me to develop the animation. So I'm going to try it out with an Animator and see what happens.
