fix: Bump Nix in CI setup to 2.2.2
...
Yants does not seem to work with older versions of Nix and I have not
yet figured out why.

feat: Introduce composable type errors and type parameter checking
...
This refactoring moves the type definitions into a recursively
evaluated attribute set, which makes it possibe to refer to types in
the definitions of other types.
This functionality is used to type-check some of the type parameters
passed in to other types. This is not yet done for all higher-order
types because the evaluation semantics of Nix make it less useful for
some cases.
Further the definition of a type itself is now a stricter
representation that works for all types except typed functions, which
allows for composable error messages.

feat: Implement support for typing functions

The defun helper takes a type signature and a function and makes a
typed version. Because we can.

test: Add some simple tests for type-checks
...
Does not currently test check failures, which makes it sort of not as
useful as you'd think.

feat: Add function type

It's not currently possible to check arguments for curried functions,
but there might be something on the horizon for attribute set
functions.
