Compatibility with other npm installers

[patrickheeney]

It looks like npm-pkgr falls back to npm when installing. I use both https://github.com/rstacruz/pnpm and https://github.com/alexanderGugel/ied for a better flat map of the npm dependencies. Could these be supported via a CLI option so that the packages can be installed via this other tools? Will this tool ever evolve into solving the same challenges as pnpm?

This tool is only about heavy caching of npm dependencies.

But I would accept any PR making it compatible with pnpm and ied yes!

Let's draft an API proposal (option names) and then implement it. You would have to do it thought because I am not heavily creating new features here :)
