Extract the memory card icons out of DRA.BIN and SEL.BIN.  I also took the opportunity to extract `g_MemcardPortMask` into its own source file `save_mgr_pre.c`. Unfortunately this is required to keep the original data order. This suggests that most likely the icon palette and bitmap were baked into the original `save_mgr.c` as byte arrays. I decided to take a different approach and extracted them as PNGs for better moddability. I had to spin-off Splat into a new fork due to some breaking changes on 0.18.0.
