This is required for Redis >= 7.x, cf.
https://raw.githubusercontent.com/redis/redis/7.0/00-RELEASENOTES:

    * MODULE and DEBUG commands disabled (protected) by default, for
      better security (#9920)

Without this patch, some unit tests fail:

```
=== RUN   TestLatency
    reply_test.go:256:
                Error Trace:    /<<PKGBUILDDIR>>/_build/src/github.com/gomodule/redigo/redis/reply_test.go:256
                Error:          Received unexpected error:
                                ERR DEBUG command not allowed. If the enable-debug-command option is set to "local", you can run it from a local connection, otherwise you need to set this option in the configuration file, and then restart the server.
                Test:           TestLatency
--- FAIL: TestLatency (0.00s)
=== RUN   TestLatencyHistories
    reply_test.go:304:
                Error Trace:    /<<PKGBUILDDIR>>/_build/src/github.com/gomodule/redigo/redis/reply_test.go:304
                Error:          Received unexpected error:

                Test:           TestLatencyHistories

```

As this not needed outside the package there's no need to export it so lower case the type name.

Also switching to semantic version naming of the parameters.

This can be improve to the following, notice a few things:

 -   It's idiomatic in go to avoid naming things get / set
 -   Wrap errors with fmt.Errorf to provide context to the user
