Add a CLI or configuration option to send logs to stderr #132

Feature Summary

For many CLI operations, it can be very convenient to rely on stdout to only have the intended CLI output (for piping purposes), and not have log messages mixed in (which can occur with config like level: trace and stdStreams: true). We would like to be able to configure and/or set the behavior so you can tell the logger to send logs only to stderr.

Problem This Solves

This makes it easier to use the CLI with piping/scripting.

Proposed Solution

A CLI argument of --log-to-stderr could work. Or a configuration option like stdStreams: 'stderr'. Or an env variable like HARPER_LOG_TO_STDERR. 🤷
