Add a CLI option to disable the timestamp in the prefix

[stack-head]

Hey, this project recently helped me out, thanks for publishing it. I'm running the same application on two different systems, and it's a bit easier to compare the logs if there's no timestamp on the messages. It's a pretty simple change but, let me know if you have any feedback.

Owner: Is there anything I can do to get this merged? I'm interested in sharing the option with collaborators, would be easier if it can get merged into the next release.

Hey maintainer, am still interested in adding this option, if you have the time.
