Aiohttp.get deprecated

[Artimi]

Hello,
I've encountered a problem with aslack and aiohttp. Aiohttp deprecated aiohttp.get() function aio-libs/aiohttp#729 in version 0.21 which is used in aslack https://github.com/textbook/aslack/blob/master/aslack/slack_api.py#L192. Problem is that in setup.py the aiohttp is constrained only to be >=0.15.0 https://github.com/textbook/aslack/blob/master/setup.py#L59 . I hotfixed this in production by pinning aiohttp to version 0.20.0, because I don't use it anywhere else in the program. Please update setup.py or better update your code to be able to have recent aiohttp.

Thanks for letting me know; I'll push a quick fix to pin the dependency, then look into adopting the session approach, as it seems like that's going to be more efficient.

v0.11.0 pins the dependency: https://github.com/textbook/aslack/blob/v0.11.0/setup.py#L59
