[request] Package as flatpak

Is your feature request related to a problem? Please describe. I run an immutable OS (Fedora Kinoite 37). Meshroom isn't available in the rpm repos, so I can't install it as a system package. I've installed it in an Arch Linux podman container with distrobox, but getting Nvidia GPU passthrough (CUDA) in the container is a massive pain. Sooo, currently I can't use the DepthMap modules.

Describe the solution you'd like I'd like Meshroom to be available as a flatpak via flathub, and able to use all features of the software (incl. DepthMap).

Describe alternatives you've considered I've checked snap, and there isn't a meshroom package there either. I could install meshroom locally somehow I'm sure, but the stock install method is messy and I'd rather not.

Additional context As far as I can tell, CUDA is available on flathub. I saw the comment below, but it's been a while so I figured it'd be good to ask.

          @bryceartstew @alcurb: For Arch-Linux you can try my packages [meshroom/alice-vision@AUR](https://aur.archlinux.org/packages/meshroom/), I can also create snap/flatpak for alice-vision/meshroom witch will provide for other distors :blush:
