Deno support

Hi.
Some packages, like tailwindcss use `detective` as a dependency. And `detective` depends on `acorn-node`, a library that doesn't work on Deno because it uses the [highly discouraged](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/proto) `__proto__` object property. I've created a version of `acorn-node` replacing the `__proto__` deprecated feature with `Object.getPrototypeOf()` and `Object.setPrototypeOf()`: https://www.npmjs.com/package/@lumeland/acorn-node

I suggest to update `acorn-node` so it would work fine in Deno environment.

FYI, I've created also a [detective](https://www.npmjs.com/package/@lumeland/detective) and [tailwind](https://www.npmjs.com/package/@lumeland/tailwindcss) temporary packages that will be deprecated if you update this package.

Thanks!
