Connection issue with RabbitMQ 4.1

Hi, thanks for this crate. I can't connect with RabbitMQ 4.1 and I believe it's related to `frame_max`. Other libs are facing the same issue, see [here](https://github.com/rabbitmq/rabbitmq-server/discussions/13616 ) or [here](https://community.n8n.io/t/not-possible-to-connect-to-rabbitmq-4-1-0/103617). Unfortunately amqprs does not allow to provide a `frame_max` parameter when connecting. So i didn't drill it further down. Setting `frame_max = 0` as a connection parameter should do the trick.
