`make analysis` implicitly relies on a `make code` run first to get the `split` package

2. Why doesn't make analysis work on its own? It seems we need the split package implicitly, and it only works on our machines (and the CI) because we typically run make code first (which pulls in the split package into the impure work cache that it pulls from).

Problem: If we clone the repo locally from fresh, and run make analysis, the external Hs script will error out for a dependency. We don't often see this error at the moment because we usually have a GHC cache that contains the dependencies (here, at least, split package).

Solution (i): We could convert the 2 relevant .hs scripts into Stack scripts and have the needed packages installed as required, automatically.

Solution (ii): Force a make code run to exist before -- seems a bit heavy for nothing.
