feat: Add async dependency resolution and enhance example

- Implemented async provider methods `toProvideAsync` and `toProvideAsyncWithParams` in `Binding` class, allowing asynchronous initialization with dynamic parameters.
- Added typedefs `AsyncProvider<T>` and `AsyncProviderWithParams<T>` for better type clarity with async operations.
- Introduced async resolution methods `resolveAsync` and `tryResolveAsync` in `Scope` for resolving asynchronous dependencies.
- Updated example in `main.dart` to demonstrate async dependency resolution capabilities.
  - Modified `FeatureModule` to utilize async providers for `DataRepository` and `DataBloc`.
  - Replaced synchronous resolution with `resolveAsync` where applicable.
  - Handled potential errors in dependency resolution with try-catch.
- Removed unnecessary whitespace for cleaner code formatting.
