This PR adds a test replicating Kim's diamond dependency example. The top-level package, `D`, depends on two intermediate packages, `B` and `C`, which each require semantically different versions of another package, `A`. The portion of `A` that `B` and `C` publicly use is unchanged across the versions, but they both privately make use of changed API. Currently, this causes a version clash. This will be made to work without error later this quarter.
