* Drop 19.09 support This is a year old. NixOS doesn't even support the last stable release, let alone the one before that. Also cuts our CI size by a third, which is always nice. * Remove 19.09 compatibility pieces

Haskell.nix Nixpkgs Pin
Haskell.nix contains several Nixpkgs pins imanaged by niv in
nix/sources.json.
These are used in testing various versions of nixpkgs.
To use haskell.nix the config and overlays need to be applied to
Nixpkgs. Users should probably pin a suitable version of nixpkgs, although things might not work for them if their Nixpkgs version is
too different.
We aim to keep this pin somewhere on a channel of the Nixpkgs latest stable release. That is currently 20.09.
We also execute tests on MacOS (darwin). The darwin channel is usually
behind the NixOS channel. So we follow the nixpkgs-20.09-darwin
channel.
