Artifact / HF finder (compass) script

[Bumber64]

Create a script that lets you know what site an artifact or HF is in, and can point you in the correct direction whether you're inside or outside the site. Ideally, there would be a GUI compass pointing to the target that updates as you move. (Can we use DF's own?)

There's an existing script that helps you find an HF, so some of the work is already done: https://gist.github.com/Sulter/b4f24de0a7d4de845e8de23ff0fdec05
