add tailwind-as-html preprocessor

[Temperantia]

Enables using tailwind classes as html attributes

[Conduitry]

Are there any other Tailwind integrations out there that support or encourage this?

I have my doubts about this feature, but if we were to add it, it would need to be in a way that doesn't add cheerio as a prod dependency for every user. It would also need to be documented, and preferably would also be opt-in.

No, it's only an idea I had a few days ago, I started using it for my own code, it feels a lot more convenient:

• "class" is no longer needed
• Elements become vertical thanks to the formatter instead of a tedious long line
• No need for class name builders
• Conditional classes can be done in Svelte

I can work on removing cheerio and document a few lines. I'm not sure what you mean by otp-in, it relies on using <template lang="tailwind">

Let me know if that makes sense

Hey, @Temperantia 👋 thanks for your idea! We already have some ways of using tailwind that are a bit more conventional (like this one or even this other one). svelte-preprocess tries to stay close to the native transformers, so your suggestion feels like a great case for a custom preprocessor.
