 * We need @sasjs/core macros at runtime for compilation of programs, but we
 * can't directly import them like a javascript file.
 * So, we have to read the macro files directly. For this we can't use the
 * node_modules folder, as it will not always be available after the library is
 * built / packed (eg in the VS Code extension)
 * Therefore, we copy the macros to a folder in the post build step, so that we
 * can read them at runtime.
 *
 * These macros are / will be used by the sasjs fs command / fs sync utilites
 * as well as for general compilation of SAS Jobs, Services, and Tests.
