What version of Dramatiq are you using?

1.3.0

What did you do?

Used the queue_name param in actor.

What did you expect would happen?

It would run without exceptions

What happened?

ValueError: Queue names must start with a letter or an underscore followed by any number of letters, digits, dashes or underscores.

Example code

import dramatiq
import requests
import sys


@dramatiq.actor(queue_name='a.fifo')
def count_words(url):
    response = requests.get(url)
    count = len(response.text.split(" "))
    print(f"There are {count} words at {url!r}.")


if __name__ == "__main__":
    count_words.send(sys.argv[1])

I've looked and found the culprit here (A regex expression to check the queue name):
https://github.com/Bogdanp/dramatiq/blob/master/dramatiq/actor.py#L26

Is there a reason on why it doesn't allow dots? Dots are needed when using fifo queues on AWS SQS. This error message appears otherwise:
Your queue name "a" contains invalid characters. A FIFO queue name must end with the .fifo suffix.

Could the solution be just changing the regex or is there a reason why dots are not permitted?
