Support a config file format that allows for comments

There’s a few ways this can be done, but wanted to open an issue to kick off some discussion.

Overall the idea is that it would be useful if a config format that allowed for comments would be supported, since then you could annotate white listings:

{
  "path-whitelist": [
    // not patchable at this time
    "1486|laravel-mix>webpack-dev-server>http-proxy-middleware>http-proxy"
  ]
}

Personally I’m a fan of JSON5, which has 1 dependency, but people also seem to like YAML for which there is YAML that has no dependencies (if you’re considered about that).

Another possible solution as a middle ground could be to support piping in a config, which would let you do json5 audit-ci.json | audit-ci.

Thoughts?

#197 should do the trick 👍🏻

+1 for the JSON 5 comment support idea.
