[Feature request] add support for modules

[sdumi]

Feature request: support for just modules.
The just modules are a great way to organize large justfiles.
But the package here does not show the recipes in modules, only the ones in the main file.

But the package here does not show the recipes in modules, only the ones in the main file.

I have been thinking on and off about this issue. I think instead of trying to show all the recipes of the other modules - it would be better to show module name in the recipe column. And the user can open a new justl buffer with just it's recipes in a new buffer instead. WDYT ?
