Use 'pcg64_fast' for RNG
...
ci/woodpecker/push/check Pipeline was successful
This is a higher quality source of randomness than a XOR-shift
generator, while still being fast and easy to write.

Make 'half_move_clock' a 'u32'
...
ci/woodpecker/push/check Pipeline was successful
It *could* be set to a high value due to e.g: starting the engine in the
middle of a game.
Moving from a `u8` to a `u32` does not change the size of the type, so
let's just do that.
Use that opportunity to fix the comment about the number of
*half-moves* (it's 50 moves *per player*).
