Published version incompatible with aioredis-2

[mephinet]

I lost some hair today trying to get the example to work - until I found out that the currently published version 1.1.2 is not compatible with the current version of aioredis.

I've seen in the repo that some work has gone into this issue by vendoring a custom version - but that's not published yet. Until this topic is solved, can you please release a new version of 1.1 with a depencency to aioredis<2 ?
This will work around the issue (and will save some beginners getting lost along the way).
Thanks!
