Friction while transitioning from CBN to chronicle_cli

[iontodd]

Hello

Since transitioning from cbn_cli to chronicle_cli, I've been missing an easy method to pass CLI arguments to the script. Retyping datetimes and filepaths when generating sample logs or testing parser changes has been slowing down my workflow.

To address this, i've been porting across the required arguments as I encounter friction. However, i'm happy to perform a more comprehensive update and submit a PR if there would be interest in incorporating these changes into the main project.
