The naming and handling of mode bitmasks have been refactored for improved code readability and maintainability. The term "Mode" was replaced with "ModeMask" for clarity and all associated functions were renamed accordingly (e.g., "SetMode" to "MaskSetMode"). These changes provide better insight into the function of the code and increase understandability for future development efforts. The command-line utility now also supports specifying modes via the "-M" flag.
