-// Bitpacked board:
-// One piece can be represented with 4 bits. Therefore, we can fit two pieces in one byte:
-// 0b0110_1110 -
-//   |          \
-//  Black king   \- White king
-// As there are 64 spaces on the board, we can pack the board into a 256-bit integer, and we use that as the index for transposition tables and such.
-// Boards are stored as a 32-byte bitfield, to make accessing them as efficient as possible.
-// We could theoretically pack it into two u128s, but some basic testing seems like LLVM can optimize array indexing faster than the bucketload of shift ops needed to pack it into u128s.
