Simplify kingRing Simplify the king ring initialization and make it more regular, by just moving the king square off the edges and using PseudoAttacks by king from this new square. There is a small functional difference from the previous master, as the old master excludes the original ksq square while this patch always includes the nine squares block (after moving the king from the edges). Additionally, master does not adjust the kingRing down if we are on relative rank 8, while this patch treats all of the edges the same.
