v12.4:
- slightly improved speed for some cards (1-2%).
- added "-gmap" option.
- a few minor changes/improvements.
Perhaps 1% improvement on 470, hard to tell, bout 299 sol/s avg on 470 8gb, bios mod
Not all cards got speedup. My tests show most speedup for Tonga cards, some Hawaii cards, but speedup is minor anyway.
