Function createWalletEventEmitter

createWalletEventEmitter(): NativeEventEmitter
Creates an event emitter for listening to wallet events.

Remarks
The emitted AddPassCompleted event payload is a raw boolean indicating whether the pass was added successfully. It is not wrapped in an object.
Example
```
const emitter = createWalletEventEmitter();
const subscription = emitter.addListener(
  'AddPassCompleted',
  (success: boolean) => {
    // success === true when the user added the pass,
    // success === false when the user cancelled.
  }
);

subscription.remove();
```
