Ignore "These packages are used outside lib/ but are not dev_dependencies"

[dodatw]

For some reason, we want to ignore "These packages are used outside lib/ but are not dev_dependencies" case. Is it possible add a config that ignore this check and return zero for pass checking ?

This seems reasonable, but just to get some more context to help decide how to implement - is it not sufficient to use the ignore: config in this case? Would it be helpful to be able to ignore other types of warnings that this tool provides, or just this one?
