Compatibility with `bevy_egui`.

[Oglo12]

I tried using this crate with bevy_egui, but it doesn't like it. The code is just incompatible. Won't even compile. It is because you require the standard Egui context.

It works.

use bevy::prelude::*;
use bevy_egui::{EguiContexts, EguiPlugin};
use egui_file::FileDialog;

fn main() {
  let mut dialog = FileDialog::open_file(None);
  dialog.open();

  let ui_example_system = move |mut contexts: EguiContexts| {
    dialog.show(contexts.ctx_mut());
  };

  App::new()
    .add_plugins(DefaultPlugins)
    .add_plugins(EguiPlugin)
    .add_systems(Update, ui_example_system)
    .run();
}
