Add support iterator

const { on } = require('events');
const { request } = require('https');
const html = require('htm');

function h(type, props, ...children) {
  return { type, props, children };
}

request('https://nodejs.org/en', async (res) => {
  const iterator = on(res, "data");
  const domIterator = html.bind(h).iterator(iterator);
  for await (const element of emitter) {
    console.log(element);
  }
}).end();

request('https://nodejs.org/en', async (res) => {
  const iterator = on(res, "data");
  const domEmitter = html.bind(h).emitter(iterator);
  domEmitter.on('div', (element) => {
    console.log('emitter', element);
  });
  domEmitter.on('end', () => {
    console.log('end');
  });
}).end();
