This adds `skipOnWin` and `skipOnUnix` to help us manage our platform-dependent tests. These methods give a nice warning message when we skip tests. We may also consider adding warnings when running platform-dependent tests. Part of the motivation for this is if we ever update to AVA v0.19. This version requires at least one assertion per test case. While this could be disabled with an AVA setting, we instead benefit from warnings for any case when we unintentionally skip assertions. This adds chalk as a dev dependency to enable colored messages.
