DeprecationWarning: Calling promisify on a function that returns a Promise is likely a mistake.

Hi,

We are using ioredis 5.0.4 which already returns Promise for all the operations.. So if we use redis-json to get/set JSON from Redis, it prints the following message to the console:

(node:13167) [DEP0174] DeprecationWarning: Calling promisify on a function that returns a Promise is likely a mistake.

I believe that's because you've wrapped the functions with promisify.

hmset: promisify(redisClient.hmset).bind(redisClient),
hmget: promisify(redisClient.hmget).bind(redisClient),
hgetall: promisify(redisClient.hgetall).bind(redisClient),
expire: promisify(redisClient.expire).bind(redisClient),
del: promisify(redisClient.del).bind(redisClient),
scan: promisify(redisClient.scan).bind(redisClient),
hincrbyfloat: promisify(redisClient.hincrbyfloat).bind(redisClient),

Any chance you can remove that and upgrade to ioredis v5? Or patch it so that you don't call promisify if ioredis ^5.0 ? Thanks!
