Summary: "flipper-pkg" added ~2MB to Flipper disttributive size, because of heavy dependencies which are only required for CLI functionality. See size warning in diff D21068373 in this stack where I added pkg as dependency to flipper. Here I'm splitting it into library and CLI packages, so Flipper app will only reference the library.
