Add read message for SQS Client

[bararchy]

It seems only new and send_message are available, is there a way to easily add get or read messages?

Is the project still maintained @sdogruyol? I'm considering using crystal with a set of aws related apps and I'm happy to take over the project.

@marceloboeira yes, it's still maintained. Any contribution is more than welcome :+1:

additionally, it would be nice if we could get a list of messages per queue :)

This would be huge for me.
