feat: implement notification proxy

[Delta456]

This PR implements the NotificationProxy service, which is used to listen to and broadcast notifications. It uses the Shim Remote RSD service.

Closes #56

A basic example using observe and receive the notification one time

await notificationProxyService.observe('com.apple.springboard.lockstate');
    const gen = notificationProxyService.receiveNotification();
    const { value: notification, done } = await gen.next();
    if (done || !notification) {
      throw new Error('No notification received.');
    }
    console.log('Received notification:', notification);

Looping all observed notifications

 await notificationProxyService.observe('com.apple.springboard.lockstate');
    const gen = notificationProxyService.receiveNotification();
    const { value: notification, done } = await gen.next();
    if (done || !notification) {
      throw new Error('No notification received.');
    }
    for await (const msg of gen) {
      console.log('Received notification:', msg);
    } // Keep the generator running to receive more notifications

Observe and post notifications

 const notificationName = 'com.apple.springboard.lockstate';
    await notificationProxyService.observe(notificationName);
    const gen = notificationProxyService.receiveNotification();
    const { value: notification, done: done } = await gen.next();
    if (done || !notification) {
      throw new Error('No notification received.');
    }
    const post = await notificationProxyService.post(notificationName);
    console.log('Received post notification:', post);
