Show weekly npm downloads for each package

This is important information when deciding between packages, it would be great to have it visible next to the package. I'm happy to try a PR for this (though I would need some support as loading this data from npm whenever benchmarks are run is a bigger change to the existing structure).

I have a better idea. Make the name of the libraries not text, but links to npm or the official website. Thus, we will not need to make requests to npm, and who wants to, will look at all the information (issues, stars, downloading) on their own

That wouldn't be that helpful. It's easier to then open up npm-stat.com and copy paste the library names. The benefit of showing it on this page is that you can see all of the packages by all the stats and decide on the best combination of performance and expected maintenance.
