Feature: Include Remote Code Files

[acederberg]

Hi!

I was wondering if I could add including files from urls (for instance from raw github content)? Obviously, this should only work for pages that are code files, e.g. some content from github raw files.

For instance, I would want this to work like something like

Some code from a repository on github:

```{.python 
     include="https://raw.githubusercontent.com/acederberg/captura/master/src/captura/fields.py"
   }
```

@cderv what are your thoughts? Is it possible to include the required dependencies when including the extension in quarto? For instance lua-http, to make requests?

Thanks for your idea. I need to check with the team if we want to allow downloading from external source here. For non computational code cell, it seems ok and we could indeed add such feature.

Pandoc's Lua API offers some fetching utility that probably can be leverage for that. See https://pandoc.org/lua-filters.html#module-pandoc.mediabag

Maybe there would be no need for a new API.

Do you want to try a PR on this for further discussion ?

Hi!

Yes I'll give that a shot here soon. Currently neck deep in some other stuff, but I think I can make this happen once I've got a minute.

Certainly that would be a problem for executable code blocks, that could enable RCE which is not desirable.
