This means we are loading and saving files with the rfd crate which
utilizes platform appropriate dialogs for saving and loading files. We
can start to use this in all other file dialog locations to make sure
we are getting the right files.
It uses xdg-desktop-portals on linux so we will always use the
appropriate file dialog for each desktop environment.
Using portals and rfd as our file selector to make sure that we can
utilize the appropriate file dialog on various platforms from
rust. This will eliminate some extra tomfoolery in QML.
