StockNemo PERFT

StockNemo being one of the fastest engine PERFT, provides PERFT results (including divide results) for all CPW (chess programming wiki) positions. Some are provided at a higher depth than the ones listed on CPW.

For readability and ease of use purposes, the divide output from StockNemo has been edited and formatted in alphabetical order. The data, including the values and time taken for computing, as well as the transposition table hits, are all accurate and kept as-is.
