Log to a file from triage CLI

[shaycrk]

In addition to logging to stdout/stderr when using the triage CLI, we should make it easier to ensure logs get captured to a file as well (although users could do this by redirecting the output, logging to a file would be good default behavior generally and providing some arguments to control it might be easier for users unfamiliar with bash).

A few features that seem like they would be useful:

• Log to a file in the project path by default, identified by the current timestamp (in addition to logging to the terminal)
• Allow specifying a log file name/path via a CLI argument
• Arguments to suppress logging to the terminal and/or file might be nice to have as well (e.g., --quiet)
