[Bug] Running render on markdown without meta will return meta from the previous run

[lil5]

Example:

const MarkdownIt = require('markdown-it')
const meta = require('markdown-it-meta')

// Make new instance
const md = new MarkdownIt()
// Add markdown-it-meta
md.use(meta)

let renderedDocument1 =  md.render('---\nfoo: true\n---\n# Foo')
let result1 = {
  document: renderedDocument1,
  meta: {...md.meta}
}

let renderedDocument2 =  md.render('# Fee')
let result2 = {
  document: renderedDocument2,
  meta: {...md.meta}
}

console.log("Result 1", result1)
console.log("Result 2", result2)

• result1.meta will be have an expected value of {foo: true}
• result2.meta should have a value of {} but 🐜 it does not and instead returns {foo: true}

Thanks for the PR! I'll take a look as soon as I can, I apologize for the slow turn around, we didn't realize this library was picking up momentum.

Looking forward to any questions or advised alterations 😉

In terms of momentum, I can only speak for myself 🤷‍♂️ idk
