[enhancement]: Official Nix support

[ketan-vijayvargiya]

Which feature or improvement would you like to request?

I am creating this issue as a followup to our conversation on the Matrix channel:

It'd be great if this project were released as an official Nix package. That would allow users (such as myself) to declaratively setup Stalwart as an email server.

Is your feature request related to a problem?

There is already a nix module created, and currently at 0.4.2.

nixos module

It is basic, but a start.

I nixfied most of 0.4.2 and it worked well, except the spam sieves, but as the stallwart project is developing at a fast pace, it is challenging to nixify the toml config options at the same pace.

A current workaround is to reference the toml files directly from within your config, which is not ideal, but gets you going.
