A couple of questions

[Scolymus]

@Bogdanp thank you for creating dramatiq! and specially this add-on.

I have a couple of questions:

1. Does this support queue priority? (Even if I have to create N SQS queues)
2. About the information at Readme, I would like to be sure about my interpretation:
   1. I don't understand "the max amount of time messages can be delayed by is 15 minutes". What do you refer to?
   2. "messages must be processed within 2 hours of being pulled, otherwise they will be redelivered." You mean that if you don't complete the task in 2h then SQS sends again the same task? Just for curiosity, if the instance shutdowns processing an element then SQS will resend again the same process after this 2h, right?
3. How does this branch evolve inside the dramatiq project? I mean, will it be updated with all bugs fixes and features coming from dramatiq github?
