Short description

We used submodules to separate rsonpath-benchmarks from rsonpath but that is no longer useful. Since rsonpath-benchmarks needs to be updated every time rsonpath is, and we want to run benchmarks every time we update rsonpath, they are very much tied together. It remains separate from the main rsonpath workspace, though, as its dependencies are completely separate.
