Also search in `%userprofile%` for profiles in Windows

I understand directories::ProjectDirs only looks in AppData on Windows but I would like for C:\Users\USERNAME\.config\rustic to be also scanned, multiple applications already use that location which resonates with Linux as /home/username is similar to C:\Users\username. I know of noone using AppData either Local or Roaming to store anything by hand, apps do use those directories but the users themselves do not.

Thanks!
