feat: add buildin loaders for simplifying usage

[AdvancedCat]

I noticed you add a feature about using react/typescript loader to transform code. Nice feature.
Maybe could let loader more simplifier by removing babel or loaders script.
like this:

<!--
<script src="https://unpkg.com/@babel/standalone/babel.min.js"></script>
<script src="https://unpkg.com/inline-module/dist/loaders.js"></script>
-->
<script src="https://unpkg.com/inline-module/dist/core.js" setup></script>

core.js can scan type="inline-script" script automatically and can check whether import babel/react/typescript loader or not.

I pull a request to review, it's counting on you.

The idea is pretty well but users may prefer other CDN files such as https://cdnjs.com/libraries/babel-standalone. I think we should give more choices to users.
