Ignore unstaged files

[dcm99]

If i run dotnet-affected against my repo with pending changes, the result is showing affected changes also caused by files that are not staged.
Is it justifiable to introduce a switch to ignore unstaged files? Or is my use case to exotic?
Reason
I use dotnet-affected in a git pre-commit hook, determing which projects are affected by the commit. In these projects I then add a "update_by_dependency.txt" file which triggers Nerdbank GitVersioning to bump the version of the affected project.

As a workaround I currently stash the unstaged files before I run dotnet-affected.
