Remove piece lists This patch removes the incrementally updated piece lists from the Position object. This has been tried before but always failed. My reasons for trying again are: * 32-bit systems (including phones) are now much less important than they were some years ago (and are absent from fishtest); * NNUE may have made SF less finely tuned to the order in which moves were generated.
