Cloning fails because of foleys_gui_magic submodule

[Bleuzen]

Hi, currently this repo fails to clone in flatpak (trying to build the collection repo, see Chowdhury-DSP/releases#1 (comment)).
End of the log:

The foleys_gui_magic submodule used here does not contain the commit (9cab1a439d86cbf7942981b24ab59c60a55b7dcd) that ChowPhaser is looking for.
GitHub also displays a warning about it:

This should be fixed now with #19. Thanks!
