allow for network imports

[seanaye]

This PR adds support for url imports in the binary executable. This allows for tailwind plugins to be imported from the internet if you aren't using node.js. e.g

import daisyui from "https://esm.sh/daisyui"
module.exports = {
  content: ['./templates/**/*.html'],
  theme: {
    extend: {},
  },
  plugins: [
    require('@tailwindcss/forms'),
    require('@tailwindcss/typography'),
    daisyui
  ],
}
