• [BREAKING] Benchmark and root paths are now interpreted relative to the
  location of the config file, instead of the current working directory.

  For example, a config at path <repo>/benchmarks/foo/tachometer.json that
  used to look as follows, and had to be run with <repo> as the cwd:

  {
    "root": ".",
    "benchmarks": [
      {
        "url": "benchmarks/foo/index.html"
      }
    ]
  }

  Should now look like this, and can be run from any cwd:

  {
    "root": "../..",
    "benchmarks": [
      {
        "url": "foo.html"
      }
    ]
  }
