Refactoring of lib.fileio.auto_open function to work with subprocess (#266)

[Reovirus]

1. CommandFormatter Interface Introduced the CommandFormatter interface, encapsulating file operations and validations.​ Added standard CLI response outputs to enhance user interaction.​
2. MODES_TO_FILES_PRESET and COMMANDS Configurations (just 2 dicts) MODES_TO_FILES_PRESET: format keys with values as lists of possible operation modes (read, write, append). COMMANDS: format and mode keys with values as dictionaries containing: tool: the tool's presence is verified in the system. command: a command formatted for substituting the number of available processors (nproc). This structure streamlines adding new formats without altering existing code.​
3. Binary File Support in CommandFormatter Added capabilities for handling binary files.​ This feature is not currently utilized but provides flexibility for future enhancements.​
4. Integration with subprocess Transitioned to using subprocess for file operations, improving compatibility and performance.​

P.S. The function signatures and responses of auto_open remain unchanged, ensuring backward compatibility. However, the implementation using the CommandFormatter class offers a more convenient and versatile approach, enhancing code maintainability and scalability.​
