v6.4.0: Progress toward macOS App Store packaging
Attempted to reduce the display complexity somewhat; still requires a lot of focus.
I believe that the signatures on the .pkg and the .app.zip should allow installation without
issue, but still not adequate for macOS App Store inclusion.
The SLIP39.app won't allow you to browse and change directory; use:
python3 -m pip install slip39
instead, and then run:
slip39-gui
