[Feature Request] Add support for HTMLRewriter

[Cherry]

Testing HTMLRewriter locally would be really awesome. Currently, ReferenceError: HTMLRewriter is not defined is just thrown when attempting to use it.

Reference: https://developers.cloudflare.com/workers/reference/apis/html-rewriter/
Cloudflare do publish the source for this too, at https://github.com/cloudflare/lol-html

Hi @Cherry! Unfortunately cloudworker is no longer actively maintained at DSC, so this is unlikely to be looked at in the near future. Perhaps we will find a volunteer at some point.

The HTMLRewriter could be integrated using cloudflare/lol-html#38

Thanks to @defjosiah I have a bit more complete HTMLRewriter shim: https://gist.github.com/grakic/b25d54f27223154023cfb3042ab66d41

Use locally with webpack.dev.js as:

    plugins: [
        new webpack.ProvidePlugin({
            HTMLRewriter: [__dirname + '/src/mock.js', 'default']
        }),
    ]

There are differences like in how it handles <div>Hello<p>World</p>Extra<br></div> but it is similar enough that it helped me debug a few issues locally.

@grakic that looks great! Thanks for extending it. Will replace our mock with that 😄

I'm going to go ahead and close this. Cloudflare's wrangler dev has taken over all of our dev use-cases and needs.
