Package FotoKilof as flatpak

[marbe36]

Is your feature request related to a problem? Please describe.
My problem is ease of installing on Linux, currently you need to copy terminal commands to install.

Describe the solution you'd like
Package FotoKilof to Flatpak and publish it on Flathub.

Describe alternatives you've considered
Package as snap on snapcraft, but snap is only available by default for Ubuntu.

Additional context
It would make installing FotoKilof easier and make it more avaiable.
