Run in parallel

[okonet]

If we have several linters defined we could run them in parallel. That would increase linting speed. And since new version of https://github.com/SamVerschueren/listr supports that, we should do.

How do I actually do this?

module.exports = {
  '*.{js,ts,tsx,json,yaml,graphql}': () => {
    return ['foo', 'bar', 'baz']
  },
};

I want to run foo, bar, baz in parallel.
