- Update to 16.1:

Browse Source 
* In our testing against its predecessor, Stockfish 16.1 shows a
    notable improvement in performance, with an Elo gain of up to
    27 points and winning over 2 times more game pairs than it loses.
  * Updated neural network architecture: The neural network architecture
    has undergone two updates and is currently in its 8th version.
  * Removal of handcrafted evaluation (HCE): This release marks the
    removal of the traditional handcrafted evaluation and the transition
    to a fully neural network-based approach.
  * Dual NNUE: For the first time, Stockfish includes a secondary neural
    network, used to quickly evaluate positions that are easily decided.
  * Use NNUE and UCI_AnalyseMode have been removed as they no longer had
    any effect. SlowMover has also been removed in favor of Move Overhead.
- Use %autosetup macro. Allows to eliminate the usage of deprecated PatchN.
