Customize error code

[make-github-pseudonymous-again]

Currently fixpack yields a non-zero error code as soon as it modifies the package.json file. Would it be possible to add a flag so that it only yields a non-zero error code when required fields are missing? My current workaround is to run fixpack twice (fixpack || fixpack)

The behavior has been recently altered in e4c9e66 but that is still not what I am after.

I'm running fixpack across a monorepo using Lerna and it would be very helpful to have the option to continue after modifying the package.json.

I agree with @make-github-pseudonymous-again.
When the package is been fixed, it still should return 0.

Opened up a PR to address this, feedback on the flag would be appreciated! #56
