Add `depRecord` to `Dep.Has` (or `Dep.Env`?) #38

For constructors that take a concrete record of dependencies (a subset of the whole set of components), a depRecord function could extract the record from the set of components.

Related to the idea (#37) of ditching the use of Has in component definitions. depRecord (and dep) would only be used in the composition root, not in the component constructors.
