The PR to implement the first version of PR vulnerability scanning was merged
so that we can have something demoable soon, but the code quality was not up
to even MVP standards (thanks Ozz and Luke for closing both eyes during review).

As I'm implementing the rest of the features for this epic, I'm also going
back and cleaning up the code and adding tests. This PR handles the package
database module.

Commit messages in the patches have more details about each patch.

The fixes include:
    - properly handle non-200 error codes
    - get rid of the separate npmPackageReply and packageJson
      structures, just parse what we need using a single struct
    - don't read the whole reply into a byte slice, use a reader instead
This will make the http queries more performant
Increases test coverage from 0% to ~90% for the pkgdb.go module
