Conduit for NixOS

Conduit can be acquired by Nix from various places:

• The flake.nix at the root of the repo
• The default.nix at the root of the repo
• From Nixpkgs

The flake.nix and default.nix do not (currently) provide a NixOS module, so (for now) services.matrix-conduit from Nixpkgs should be used to configure Conduit.

If you want to run the latest code, you should get Conduit from the flake.nix or default.nix and set services.matrix-conduit.package appropriately.
