Time / Date on Output Screen

I love this extension and use it all the time. Thank you!

As a feature request, it would be useful to have an option where the date/time shows up in the output screen. Sometimes I run the code several times in quick succession after making a tiny modification and would like to verify the change's output. Since the code runs so fast to the output screen, I cannot tell whether the output on the screen is remaining from the time before or whether it is fresh output from having just run the `run code` option again.

A date/time stamp would enable people to see that there is a difference in the time stamps (maybe even just a few seconds) and therefore it would be a new run.

I have been able to use the `code-runner.clearPreviousOutput": true,` setting, however this means that the screen is cleared down completely and it is useful to be able to browse the history as well as a temporary work-in-progress buffer log.

Perhaps there is an option for you to provide options to leverage the `Show Execution Message` option to allow someone build their own execution message which could incorporate the date/time. Alternatively, a separate option could be used.

I have checked the VS Code docs, settings in `settings.json,`a search of Google and the existing open issues raised in this repo and cannot seem to find this option at the moment.
