Updated mode tests to include a new Mode, ModeHumanReadable, and created an additional test case, ModeComplexNoHumanReadable. This was done because a more human readable mode was required for some use cases. Also added a test function TestMode_String to ensure the .String() method of each mode works as intended.
The ordering of modes in the existing test was changed to logically group them together. In addition, a new test was added, `TestModesFromFlags`, to cover multiple different conditions including complex modes and cases where certain mode elements are excluded. This expansion in testing enhances our coverage of varied mode settings.
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.
Refactored the generator to include a new config option, changed function signatures to follow the new structure, and renamed the function 'RandomString' to 'RandomStringFromCharRange' for clarity. Also, added a new mode and algorithm feature to enhance password generation. Furthermore, added several tests for new features and configurations. Adapted the CLI to use the new configuration approach. This refactoring was necessary to improve the customizability and clarity of the password generation process. Fixed minor issues and added '.gitignore' for clean commits in the future.
