strict_map_key

New msgpack from version 1.0.0 has strict_map_key=True, so exception for int casting for value is thrown when using Django Redis cache here https://github.com/jazzband/django-redis/blob/master/django_redis/client/default.py#L482

Fast fix for me was to change from return msgpack.loads(value, raw=False) to return msgpack.loads(value, raw=False, strict_map_key=False)
