  1. Introduce opening book support 

    My study have shown that it does no harm to use an opening book instead of a search, while the latter being largely deterministic.

This is a primitive version, using a PolyGlot-like book format but with our own Zobrist hash keys, so the probing might be cheap enough to be used elsewhere in search.

The burden is on the creation of the book to provide more diversity to the openings and cover some corner cases, which is another area of research.

No functional changes without a book.
