UB2 now signs and notarizes, upgraded to SDL 2.0.16

Also works on Apple Silicon. Specific signing values are in a non-committed file, and the ub2 script only notarizes if a "notarize" flag is passed in on the command line.

NOTE: the SDL dylib currently only has x86_64 and arm64, will need extra work to graft those back in and keep the Notary service happy.

* Allocate and free an RGB surface.
* Allocate a new RGB surface.
*
* If the depth is 4 or 8 bits, an empty palette is allocated for the surface.
* If the depth is greater than 8 bits, the pixel format is set using the
* flags '[RGB]mask'.
* If `depth` is 4 or 8 bits, an empty palette is allocated for the surface.
* If `depth` is greater than 8 bits, the pixel format is set using the
* [RGBA]mask parameters.
*
* If the function runs out of memory, it will return NULL.
* The [RGBA]mask parameters are the bitmasks used to extract that color from
* a pixel. For instance, `Rmask` being 0xFF000000 means the red data is
* stored in the most significant byte. Using zeros for the RGB masks sets a
* default value, based on the depth. For example:
*
* \param flags The \c flags are obsolete and should be set to 0.
* \param width The width in pixels of the surface to create.
* \param height The height in pixels of the surface to create.
* \param depth The depth in bits of the surface to create.
* \param Rmask The red mask of the surface to create.
* \param Gmask The green mask of the surface to create.
* \param Bmask The blue mask of the surface to create.
* \param Amask The alpha mask of the surface to create.
* ```c++
* SDL_CreateRGBSurface(0,w,h,32,0,0,0,0);
* ```
*
* However, using zero for the Amask results in an Amask of 0.
*
* By default surfaces with an alpha mask are set up for blending as with:
*
* ```c++
* SDL_SetSurfaceBlendMode(surface, SDL_BLENDMODE_BLEND)
* ```
*
* You can change this by calling SDL_SetSurfaceBlendMode() and selecting a
* different `blendMode`.
*
* \param flags the flags are unused and should be set to 0
* \param width the width of the surface
* \param height the height of the surface
* \param depth the depth of the surface in bits
* \param Rmask the red mask for the pixels
* \param Gmask the green mask for the pixels
* \param Bmask the blue mask for the pixels
* \param Amask the alpha mask for the pixels
* \returns the new SDL_Surface structure that is created or NULL if it fails;
