A small babashka script to convert HTML from stdin to hiccup and pretty print it.

I use this inside NeoVim with this config line

```
command PasteAsHiccup r !pbpaste | html2hiccup
```

And then whenever I want to paste some HTML as Hiccup I'll do `:PasteAsHiccup`. 

This requires

1. `bb` (Babashka)
2. `zprint`
3. The script below in your `$PATH`
