Use in CI Systems

As this is likely not a one-time problem, it would be good to be able to integrate this as a part of your CI pipeline.

Thoughts:

• The tool can wrongly target a package as being unused, this might be because we don't actually see the package in the code. Think apollo or graphql or the tool is making a mistake.

• We can partially mitigate the above, by allowing users to configure accepted packages or ignored packages in #3 so we can check against those

• This likely should be used as a fail condition on CI systems but rather something like codecov or something, it can generate the report and add it as a PR comment

There is a bug where the module does not work correctly in CI systems and causes issues
