Consume Logs

Now let's consume the logs and save them to disk.

Assignment

Create a .gitignore file if you don't already have one and ignore all files ending in .log:

*.log

Add a SubscribeGob function to the internal/pubsub package. It should be similar to the SubscribeJSON function, but decode from gob instead of JSON.

I used generics to create a helper function to share duplicate code between SubscribeJSON and SubscribeGob. If you're curious this was the function signature of the helper:

func subscribe[T any](
	conn *amqp.Connection,
	exchange,
	queueName,
	key string,
	simpleQueueType SimpleQueueType,
	handler func(T) Acktype,
	unmarshaller func([]byte) (T, error),
) error

Update the server to SubscribeGob to the game_logs queue instead of just declaring it. Use a wildcard in the routing key to make sure you capture logs from all clients, no matter the username. The handler should:
1. Defer printing a new prompt to the console.
2. Use the gamelogic.WriteLog function to write the log to disk.
Test the code.
- Because your queue has some logs in it, you should see them get consumed as soon as you restart the server.
- Make sure that the game.log file contains the logs you expect.
- Ensure all the messages from the game_logs queue are consumed using the Rabbit UI.

Run and submit the CLI tests.
