Change to nativefiledialog-extended

[Suavesito-Olimpiada]

The original library nativefiledialog was still active when I created this wrapper. Now two years have passed, and the repo seems dead; with many issues and Pr's in wait and without answers.

It also lacks some features which are desired by some Julia users (as dialog title).

At that time, the fork nativefiledialog-extended already existed, but it didn't look as mature as the original. Now that the upstream looks dead, maybe it's time to reconsider the change.

It looks like nativefiledialog-extended supports SDL2 alongside GTK, perhaps we can change to SDL2 if it weights less and loads faster.

Any progress on this? What would be the required steps to do this?

I'm currently working on generating the artifact for nativefiledialog-extended.
