Check resolutions

[ghost]

The resolutions field of package.json contains version specifications for modules-of-modules. I would like it if npm-check-updates could check these dependencies as well.
The two main use-cases for the field are to either pin a dependency to a specific version (e.g., for compatibility) or to keep the versions in sync across modules (e.g., for smaller webpack bundles).
I'm interested in use-case 2, and for me that means I have to manually update the resolutions field to match dependencies after every ncu. It would be nice if ncu could do it for me.
To support use-case 1, it shouldn't check this field by default; it needs to be opt-in, so a flag and/or a configuration option would be needed.
