AttributeError: 'float' object has no attribute 'items' (redis 3 compatibility)

Current implementation/example doesn't work with redis>=3:

Traceback (most recent call last):
  File "test.py", line 9, in <module>
    f(3) # This will print "Calling f(3)", will return 3
  File "/home/devin/.local/share/virtualenvs/redis-fun-0aEUqbK5/lib/python3.6/site-packages/redis_lru/lru.py", line 48, in inner
    return lru_cache[key]
  File "/home/devin/.local/share/virtualenvs/redis-fun-0aEUqbK5/lib/python3.6/site-packages/redis_lru/lru.py", line 64, in wrapper
    return method(self, key, *args, **kwargs)
  File "/home/devin/.local/share/virtualenvs/redis-fun-0aEUqbK5/lib/python3.6/site-packages/redis_lru/lru.py", line 224, in __getitem__

    return iter(x.items())
AttributeError: 'float' object has no attribute 'items'

Pinning redis at redis==2.10.6 fixes this.
