Added a new unit test, TestSpell, to the spelling_test.go file. This new test safely triggers several different spell checking scenarios, from empty strings to non-alphabetical characters. As a result, the function's reliability and robustness is significantly improved.
Modified the error messages in spelling tests within spelling_test.go to improve clarity and readability. These adjustments involve changing the format specifiers in the error messages of 'ConvertByteToWord' function tests to correspond with the expected data types for better error reporting.
The update introduces a new 'SpellPassword' setting in the configuration that, when enabled, spells out the generated passwords in the phonetic alphabet. The accompanied changes include the addition of 'spelling.go' and 'spelling_test.go' files containing the spelling logic and corresponding tests. The domain-specific error handling is also enhanced for unsupported characters.
