fakeredis.aioredis.FakeRedis to support version selection

[steve-mavens]

Is your feature request related to a problem? Please describe.

I'm still using Redis 6, so it would be useful to run tests in Redis 6 compatibility mode. This is supported for the blocking client, but doesn't work for the asyncio client:

>       async with fakeredis.aioredis.FakeRedis(decode_responses=True, version=6) as client:

tests\test_redis_client.py:33:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

...SNIPPED...

            db=db,
            password=password,
            socket_timeout=socket_timeout,
            connection_pool=connection_pool,
            encoding=encoding,
            encoding_errors=encoding_errors,
            decode_responses=decode_responses,

            health_check_interval=health_check_interval,
            client_name=client_name,
            username=username,
            **kwargs,
        )
E       TypeError: Redis.__init__() got an unexpected keyword argument 'version'

Describe the solution you'd like

fakeredis.aioredis.FakeRedis to support the same version parameter as fakeredis.FakeRedis

Describe alternatives you've considered

redislite, testing against real redis instance. These are sub-optimal for the same reasons fakeredis in general is good.
