Report number of dependencies and overall install size

[benmccann]

Basically the stuff on https://pkg-size.dev/ but available via this library which returns other useful stats as well

How many dependencies are CJS vs ESM would be a bonus similar to node-modules.dev

If we're already installing the package hopefully this wouldn't require extra network calls

dunno if we're gonna expand further on this issue @43081j, but i think this can be closed 😁

we still have work to do but can open follow up issues for it 👍

since now we do show the size but still have some ux changes to make
