Parses Redis commands to get command keys.
COMMAND output is used to determine key locations.
Commands that do not have a predefined key location are flagged with
'movablekeys', and these commands' keys are determined by the command
'COMMAND GETKEYS'.

Get the keys from the passed command.
NOTE: Due to a bug in redis<7.0, this function does not work properly
for EVAL or EVALSHA when the `numkeys` arg is 0.
- issue: https://github.com/redis/redis/issues/9493
- fix: https://github.com/redis/redis/pull/9733
So, don't use this function with EVAL or EVALSHA.

Get the keys from pubsub command.
Although PubSub commands have predetermined key locations, they are not
supported in the 'COMMAND's output, so the key positions are hardcoded
in this method
