Support for hyperlinks

EDIT: See sindresorhus/terminal-link

---

Trivial implementation:

function hyperlink(text, url, attrs) {
  return `\u001b]8;${attrs || ''};${url || text}\u0007${text}\u001b]8;;\u0007`;
}

Usage:

console.log(
  `See issue ${
    hyperlink('#319 on GitHub', 'https://github.com/chalk/chalk/issues/319')
  }`
);

@langpavel I would be happy to add support for stderr in terminal-link 😉

I think it’s way too early to add this to Chalk, if at all. I like to see it more widely supported first. For now, we can just recommend terminal-link. Honestly not even sure if it makes sense to have this in Chalk. Chalk is for visual styling, while hyperlinks are functional. This is a slippery slope. If we accept this, we should expect to get requests to support other ansi escape codes, like hiding the cursor, etc.
