Subject: [PATCH] Update readme to replace --level option with -O

This change removes mention of the `--level` option which never existed. In versions earlier than 5.0.0, clean-css-cli used to accept the invalid option silently.  With versions > 5.0.0, trying to use the option results in the following: `error: unknown option '--level'`.  The root cause of the change the upgrade to [commander v7.0.0](https://github.com/tj/commander.js/pull/1409), where unknown (excess) command arguments are now raised as an error.
