[Ehancement] Redis version check before start up?

[zerg000000]

I am very interested in adding a Redis version check before starting.

Because it is very hard to debug and carmine-streams don't have any doc showing the minimum version of the required Redis.

If it is too much, a separate function to check if the Redis version is supported would also be very helpful.

Hello,

Could definitely add a function to call which would tell you if it's compatible or not

For clarity, you need Redis v7 for the full set of features in v2.x. v1.x should work with Redis 6

[zerg000000]

is this fn enough to do the checking?

(defn compatible? 
  [conn-opts] 
  (let [[_ version] (->> (car/wcar conn-opts (car/info :server))
                         (re-find #"redis_version:([0-9])"))] 
    (>= (parse-long version) 7)))

Looks good, do you want to make a PR?

Cheers
