feat: add the ability to log directly to a file

[evan-forbes]

Overview

This PR simply adds the option via a new flag to log directly to a file. This feature was requested by @Bidon15 to not have to use the &> in the cli. If this turns out to be a desirable feature, we can easily expand on this in the future.

Checklist
