update screen transition

[shpasha]

A slightly different approach to screen transitions. Now the active screen (the one we push) determines the animation. We already have this approach in our approach and it is very convenient.

I also added lastEvent to the enter/exit to understand the slide direction

@DevSrSouza If there are no more problems, maybe we can merge the request?

@shpasha Can you update this docs @shpasha https://github.com/adrielcafe/voyager/blob/main/docs/transitions-api.md ?

Adding the new ScreenTransition function and some examples using delegate implementation, etc.
