SDL_INIT_INTERFACE - A macro to initialize an SDL interface.

       This macro is available since SDL 3.2.0.

       This macro will initialize an SDL interface structure and should be called before you fill out the fields
       with your implementation.

       You can use it like this:

              SDL_IOStreamInterface iface;

              SDL_INIT_INTERFACE(&iface);

              // Fill in the interface function pointers with your implementation
              iface.seek = ...

              stream = SDL_OpenIO(&iface, NULL);

       If you are using designated initializers, you can use the size of the interface as the version, e.g.

              SDL_IOStreamInterface iface = {
                  .version = sizeof(iface),
                  .seek = ...
              };
              stream = SDL_OpenIO(&iface, NULL);
