Flatpak support

[DRSchlaubi]

The ability to build distributions for compose applications is really useful, however, only supporting dpkg is very limiting.

Because supporting every package manager out there might be a lot of work, mit would make sense to distribute the application as a flatpak as it's independent of the linux distribution

It shouldn't be too hard to implement I might do a PR if you're interested in supporting it.

@AlexeyTsvetkov That do you think? Do we need support of flatpak distribution?

This would be amazing to have.

This would be amazing to have.

You can do that now, I have my app on flathub although it requires some additional setup

[DRSchlaubi]

But first party Support would be great for more modern formats like flatpak and msix, sadly oracle doesn't seem to really have plans to add them to jpackage, however adding them is still fairly easy

There are more and more requests for flatpak. Just got one more from a user.
