 * Obtains and splits a promise into its individual `then`, `catch`, and `finally` components, already bound and ready to be destructured.
 * 
 * The given object is forced to be a promise using `Promise.resolve`.
 * 
 * @example
 * 
 * const { then, catch, finally } = unpack_promise(Promise.resolve(27));
 * 
 * then(console.log); // 27
