Bruno BELANYI a4aa4ae1e4 Make 'half_move_clock' a 'u32'
All checks were successful
ci/woodpecker/push/check Pipeline was successful
Details 
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*).

This makes more sense from a user's perspective.

Bruno BELANYI b9cc60be9c Use 'ChessBoardBuilder' in 'FromFen' 
This will allow taking this *out* of the module, now that we don't need
to reach into the internals of 'ChessBoard'.

Bruno BELANYI a676094dc1 Use 'ChessBoardBuilder' in validation tests 
The various tests for overlapping can't be triggered with the builder
API, so those have stayed unchanged.

It wasn't actually testing the right thing due to the typo...

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`...
