short import

[Cologler]

Use from asq import query instead of from asq.initiators import query.

I read the readme.md every time when I try to use this library.

So sad.

We just need in __init__.py

from .initiators import query  # noqa

and in test_asq.py change

from asq.initiators import query

to

from asq import query
