Nix Flakes

This adds required files for nix support, and some documentation to README.md on how to use them.

It should be compatible with x86_64-linux, aarch64-linux and x86_64-darwin platforms. All built binaries are working. Built Nix package also contains udev rules, so if you install it in NixOS, it will apply rules automagically.

FIrst and foremost, thank you for your input!

As there is no proper package managers support yet, may I ask you to do the following as well:

1. Create a separate directory called packages/nix or something like that
2. Create a general packages/README.md and a nix-related packages/nix/README.md
3. Put all nix-related files into the packages/nix directory
4. Make the necessary links from the main README.md, removing all specific information from it

This configuration would allow for easier integration with other package management systems later.

NB: You might also want to disable the automatic update feature via DISABLE_APPLICATION_UPDATES as it doesn't really make sense to have it enabled in a system package.

Can I call the directory "contrib" instead of "packages" though? This is a standard for contributions, and is present in many other open-source projects.

Thank you, that's something I was searching for :heart:

Yep, that sounds about right.

[cab404]

@gsurkov I've applied your suggestions to current packaging, and expanded documentation.

I can also add Nix CI job, if you want

This is OK as it is, thanks.
