Suffers infinite recursion due to the QuickCheck override.
The cabal.project file has constraints on hashable and semigroups that mean we need newer versions when doing `cabal v2-*` builds. This commit adds those constraints, as well as a flag to disable them when not using `cabal v2-*`.
This is already being done for `aeson-1.4.3.0` and saves us bumping the aeson version in our nix.

@ajmcmiddlin We could easily pin with the setup that I uploaded by pinning in default.nix. I actually deliberately decided NOT to pin (in the overlay would be fine to pin in default.nix) because this is a library that is presumably used by many different people, who might want to pin to different versions of nixpkgs themselves. The overlay is generally useful enough that I think people will be able to use it with somewhat different versions of nixpkgs, and it automatically plugs in nicely with existing nix setups. |

Yeah, that all makes sense. I'll use your setup and maybe raise a PR for taking nixpkgs as an argument in |

While I was working on #380 I (with the help of some team mates) updated the nix setup. @IvanMalison updated the nix setup before I cleaned up my changes and put them in a PR. I thought I should still raise this version, as it takes a different approach that may be preferable.
The key difference here is that
nixpkgsis (by default) pinned to a specific commit, such that this setup should always work regardless of the user'sNIX_PATH(where<nixpkgs>comes from).I've tested this with both
nix-buildandnix-shell --run "cabal v2-build github".
