Allow EVAL/EVALSHA to read from replicas

[rtkefreure]

Based on this comment
redis/redis#8537 (comment)
it looks like it should be possible to send an EVAL/EVALSHA command to a replica in cluster mode (as long as the script commands are all readonly). It looks like this library explicitly prevents all EVAL/EVALSHA commands from running against replicas. Is that correct? If so, would it be possible to add in a new feature to allow EVAL/EVALSHA to run on replicas?
Thanks
