haskellPackages: Add myself (turion) to maintainer list

[turion]

Motivation for this change

I just noticed that it is now possible to specify maintainers for specific Haskell packages. Here are those that I already maintain on Stackage.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Side note: Wouldn't it be nice to automatically populate this list with the intersection of nixpkgs and Stackage maintainers?

@turion Thanks for adding yourself here!

Please make sure that all the packages you've listed here are currently building and not marked broken.

I don't think we have any automatic process for notifying you if the packages get marked broken, but sometimes @peti will ping you in a comment.

I had a look, pretty sure that this is the case.

Maybe we should look into having one? I don't know whether nixpkgs has such a mechanism in general. If it had, we might hook into it somehow. If not, we could still look into writing our own little bot for that maybe?
