Poly 1.5 - Book tuning by WDL

[Rebel]

The next step in the evolution of the Polyglot book is to add a WDL (won | draw | loss) statistic to book moves offering the following advantages:

1. Make the WDL visible, see the example made with the latest ProDeo;

2. Tuning the weight using the WDL instead of the Stockfish evaluation score.

3. Insight in your personal opening repertoire, what opening to play or avoid.

For number 2, I would suggest that both pieces of information are valuable.
Also, the type of measurement affects how trusable it is,
Consider a 50 ply search by SF, or a one hour search by LC0
I trust those measurements a lot,
Shall we replace the move suggestion and score with information based on 15 games?
On the other hand, if we have a hundred thousand games between high end opponents, then this data is also highly trustable

So I think that we should store the raw data for both measurements and then let the engines use it how they want

Absolutely, all the information is available for the engine programmer.

Maybe something for the next version, it should work for non-programmers as well.
