Support for nanobench

[mcandre]

The Quick Bench online tool is a great resource for sharing benchmark analysis. I see that Quick Bench currently supports the Google benchmark framework. Could you please also add support for nanobench? It is another popular library that some developers use instead of Google benchmark.

nanobench uses fewer resources than Google benchmark, and so would run smoother for the online Quick Bench tool if you made this available as an option.

I am not sure how you are managing dependencies. For what it's worth, there is a conan package available to make nanobench easier to install.
