Stormphrax 7.0.0 - what's new?
it's been a while!
Stormphrax 7.0.0 is much stronger than 6.0.0, now supports MultiPV, and has a significantly larger and more complex network. As standard, the regular search tweaks, plus massive code quality improvements across the board :3
Many thanks again to everyone who has contributed CPU time to the OpenBench instance that Stormphrax is tested on - now too many to list, but in particular @JouanDeag for contributing hosting together with @noobpwnftw for a constant presence of workers, @KazApps (big up the Big Worker), and @cosmobobak.

Elo testing done with Fishtest's UHO_Lichess_4852_v1.epd book for standard chess and DFRC_4852_v1.epd for DFRC.
Results are obtained from self-play and will likely not scale perfectly to games against other opponents :)
Support for x86 CPUs lacking AVX2 has been dropped.
