craftax: reorg to top-level config + shared resources dir

- config/ocean/craftax.ini -> config/craftax.ini
- config/ocean/craftax_classic.ini -> config/craftax_classic.ini
- ocean/craftax/textures.bin -> resources/craftax/textures.bin
- scripts/craftax_convergence_bench.py -> tests/craftax_convergence_bench.py
- drop empty scripts/ directory
- pack_textures.py: write to resources/craftax/textures.bin
- craftax.h / craftax_classic.h: fopen textures from resources/craftax/
