futari-linux 1.2.1 (x86-64 and AArch64)

Fixes a crash when 1.2.0 was extracted over a 1.1.0 folder. The old vulkan_spirv.bin from the installer page stayed next to the program and was used instead of the built-in shaders, which could crash the game (for example when opening the options screen). The program now ignores that file. It can be deleted.

Install and update the same way as 1.2.0: extract the archive for your processor, put your ISO next to futari.sh or your game files in game_root, DLC in dlc, and start futari.sh.
