Bruno BELANYI 52772167a6 Pre-generate the magic bitboard seeds
My naive RNG implementation takes about ~40 seconds to generate the
magic bitboards for both bishops and rooks (or ~1 second in release
mode).

If we pre-generate the seeds, we can instead make it ~instantaneous.

The self-modifying code is inspired by matklad [1].

Bruno BELANYI c1419f0e44 Add FEN board parsing
Unfortunately, given that I *don't* want to expose all the `ChessBoard`
fields to the rest of the crate, this implementation will have to live
alongside its module instead of inside `crate::fen`...
