Bump aeson from 1.5.* to 2.0.*

[ReinierMaas]

XRef: #118

This is the first try to overwrite the packages such that stack can compile with aeson 2.0.* available.

This adds a Haskell overlay in the process.

This overwrites the minimal set of packages in the ./nix/haskell-overlay.nix to enable aeson 2.0.*.

---

The current state is that the dependencies compile but the package itself needs to be modified to work with the updated aeson package.

I couldn't get static binary to work on this branch so am currently building that on the master branch to see if it was working on my machine. I will then work my way up to the GHC migration branch and get it to compile there with the newer stackage LTS version and necessary Hackage snapshot. Later I can try to make it compile with this branch where certain packages are overridden.

Update this didn't work on master.
