Including images and code in descriptions

[Mc-Zen]

This module of course needs eval() to evaluate function and parameter descriptions, meaning that no other than the built-in functions can be called.

Also, the filesystem cannot be accessed within eval()ed code. Despite that, image() currently works through a workaround but since packages don't have access to the filesystem as well, this will cease to work when installed as a package (which will soon be possible) :/

Luckily the next Typst version (0.7.0) adds a scope parameter to eval() that allows passing a dictionary of symbols to be passed that are then available in the eval context. I plan on allowing a similar parameter for the function parse-module().

If everything goes well, then the user may even pass a module here and then use all of its definitions which will mean that rendering of code examples will be possible in function or parameter descriptions.

This feature could also be used to include images in some way.

Please give feedback if this would be useful and maybe what form would be best regarding your project's requirements :)
