The PV line that follows might\nnot preserve the game outcome, but can easily be verified and extended based on\nTB information. This patch provides this functionality, simply extending the PV\nlines on output, this doesn't affect search.\n\nIndeed, if DTZ tables are available, search based PV lines that correspond to\ndecisive TB scores are verified to preserve game outcome, truncating the line\nas needed. Subsequently, such PV lines are extended with a game outcome\npreserving line until mate, as a possible continuation.  These lines are not\noptimal mating lines, but are similar to what a user could produce on a website\nlike https://syzygy-tables.info/ clicking always the top ranked move, i.e.\nminimizing or maximizing DTZ (with a simple tie-breaker for moves that have\nidentical DTZ), and are thus an just an illustration of how to game can be won.\n\nA similar approach is already in established in\nhttps://github.com/joergoster/Stockfish/tree/matefish2\n\nThis also contributes to addressing #5175 where SF can give an incorrect TB\nwin/loss for positions in TB with a movecounter that doesn't reflect optimal\nplay. While the full solution requires either TB generated differently, or a\nsearch when ranking rootmoves, current SF will eventually find a draw in these\ncases, in practice quite quickly, e.g.\n`1kq5/q2r4/5K2/8/8/8/8/7Q w - - 96 1`\n`8/8/6k1/3B4/3K4/4N3/8/8 w - - 54 106`\n\nGives the same results as master on an extended set of test positions from\nhttps://github.com/mcostalba/Stockfish/commit/9173d29c414ddb8f4bec74e4db3ccbe664c66bf9\nwith the exception of the above mentioned fen where this commit improves.\n\nWith https://github.com/vondele/matetrack using 6men TB, all generated PVs verify:\n```\nUsing ../Stockfish/src/stockfish.syzygyExtend on matetrack.epd with --nodes 1000000 --syzygyPath /chess/syzygy/3-4-5-6/WDL:/chess/syzygy/3-4-5-6/DTZ\nEngine ID:     Stockfish dev-20240704-ff227954\nTotal FENs:    6555\nFound mates:   3299\nBest mates:    2582\nFound TB wins: 568\n```\n\nAs repeated DTZ probing could be slow a procedure (100ms+ on HDD, a few ms on\nSSD), the extension is only done as long as the time taken is less than half\nthe `Move Overhead` parameter. For tournaments where these lines might be of\ninterest to the user, a suitable `Move Overhead` might be needed (e.g. TCEC has\n1000ms already).\n\ncloses
