 * Allows you to make changes to the JSON read from an open HAR file

 * The transform is consumed when `routeFromHAR()` opens the dump, so it has to be
 * registered before `initDumps()` / `routeFromHAR()` — at module level or in a
 * fixture that runs earlier. Registering it after a dump has already been opened
 * in the worker throws. The first call wins for the whole worker process; later
 * calls are ignored with a warning.
