Rank-based outposts 

Introduce OutpostRank[RANK_NB] which contains a bonus according to the rank of the outpost. We use it for the primary Outpost bonus. The values are based on the trends of the SPSA tuning run with some manual tweaks. 

Passed STC: 
LLR: 2.96 (-2.94,2.94) [-1.50,4.50] 
Total: 27454 W: 6059 L: 5869 D: 15526 Elo +2.40

Passed LTC: 
LLR: 2.94 (-2.94,2.94) [0.00,3.50] 
Total: 57950 W: 9443 L: 9112 D: 39395 Elo +1.98

---------------------------- 
The inspiration for this patch came from Stefan Geschwentner's attempt of modifying BishopPawns into a rank-based penalty. Michael Stembera suggested that maybe the S(0, 0) ranks (3rd, 7th and also maybe 8th) can still be tuned. This would expand our definition of Outpost and 
OutpostRanks would be removed altogether. Special thanks to Mark Tenzer for all the help and excellent suggestions.

Shallow depth pruning on NonPV advanced pawn push 

Usually advanced pawn pushes are not considered in shallow depth pruning because it is risky to do so with possible promotions near the horizon. 
However, this heuristic is not also beneficial on NonPV nodes since we can afford to take slightly more risk on less important nodes.

Chess engine: BrainFish 191106 and Cerebellum Light 190804

Brainfish - UCI chess engine, JCER Rating=3217

From the author:
Brainfish is a standard Stockfish chess engine extended by a general book format that is capable of handling a reduced part of Cerebellum, which is an innovative chess opening and playing book. In Brainfish, the book moves are only used in engine games, not in analysis mode.

All moves in the published book Cerebellum_light.bin generated by Cerebellum were calculated by using
Stockfish as analysis engine, without using statistics. Then those moves where recalulated by the Cerebellum Library using a graph algorithm that makes all scores in the library consistant. Consistant scores means for example, in case the starting position has a score of 0.2 and a best move is 1.e4, the position after 1.e4 must have the score -0.2. Additionally, some others properties are found, like the best main line of a position and possible Transitions.

Hence, when Brainfish is playing moves that are in the Cerebellum book, it plays like Stockfish regarding the evaluation, only at a much higher skill level. Pondering is only active after the last move out of the book has been played.

Chess engine: Stockfish 2019-11-06 Polyglot

Stockfish - UCI chess engine
INTRODUCTION:
Due to the missing of this feature in the main release I have decided to create a Stockfish perfectly equal to the last beta version with the capability to use Polyglot books (aka .bin or BIN). In order to do that I used the library polyblook from Brainfish and merged with the Stockfish code.
