Add phonetic spelling functionality to password generator
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.
