Future sample usage of NatsConsumer

NatsConsumerSample.cs

public Task Alternative1() {
  var consumer = new NatsConsumer(client);
  var subscription = await consumer.SubscribeAsync("mySubject", msg => {
    //do something with the message
  });
  
  //time goes by
  
  subscription.Dispose(); //issues client.Unsub(subject) against NATS broker as well as removes handler
  
  consumer.Dispose(); //for any non disposed subscriptions, it issues client.Unsub(subject) against NATS broker as well as removes handler
}

public Task Alternative2() {
  var consumer = new NatsConsumer(client);
  var subscriptionId = await consumer.SubscribeAsync("mySubject", msg => {
    //do something with the message
  });
  
  //time goes by
  
  await consumer.UnsubscribeAsync(subscriptionId); //issues client.Unsub(subject) against NATS broker as well as removes handler
  
  consumer.Dispose(); //for any non unsubscribed subscriptions, it issues client.Unsub(subject) against NATS broker as well as removes handler
}

public Task Alternative3() {
  var consumer = new NatsConsumer(client);
  var subscription = await consumer.SubscribeAsync("mySubject", msg => {
    //do something with the message
  });
  
  //time goes by
  
  subscription.Release(); //issues client.Unsub(subject) against NATS broker as well as removes handler
    
  consumer.Dispose(); //for any non unsubscribed subscriptions, it issues client.Unsub(subject) against NATS broker as well as removes handler
