TODO eventually

- [x] fix being an 'alternate service' - Maybe a less stupid name? - lol never - [ ] allow `nixpak-flatpak-wrapper` to be installed without `flatpak`. - add dummy flatpak wrapped binary? - [ ] per-user configuration. This is pretty import for Proper (TM) home-manager modules to integrate with nixpak-flatpak-wrapper. I myself was wanting to do this just today with my personal Firefox module.
