Updated example

I had to make the following changes to get it to run

`
//import mail2pdf from 'mail2pdf';
//import { promises as fs } from 'fs';

const fs = require('fs.promises');
const mail2pdf = require('mail2pdf');

(async () => {
// Simply call the mail2pdf() function with the email (or
// emails as an array) you want to convert. You can also
// pass additional options, see below for details.
const pdf = await mail2pdf('email.eml', { language: 'en' });
// The resulting PDF is returned as a Buffer that you can
// save to disk for example.
await fs.writeFile('sample.pdf', pdf);
})();
`
