Formatting fails when one justfile imports another #76
Description
If one justfile imports another, like import "../justfile", then copying the justfile we're editing to a temporary directory and running just --fmt --unstable doesn't work. This is the current approach taken by this project here.
Instead, we can run just --dump --justfile {filename}" with the full path to the file. This also allows for non-standard filenames like something_else.just.
