Architecture choice

The chess game is modeled with sealed class and switch implemented in JDK 21. Choice was made considering the number of piece in the board are fixed and cannot be extended. This allow static dispatch implemented in ChessPiece base class and PieceLogic where all the logic of piece movement and validation is centralized and specialized piece logic is dispatched. Project is implemented using vavr library to use a more functional style programming taking in consideration immutability and referential transparency of the functions. The entry point is class ChessConsole that will execute the moves contains in the file txt passed as input. Missing some tests and more validation for edge cases.
