Add more naming strategies/formats enum types

[tomroffe]

HI 👋,

Please excuse the uninvited PR, but I thought to share just in case someone else found this useful. Please let me know your thoughts on including, and ill be happy to adapt. 😄

I needed the format of the generated names to be slightly different. To allow this, I adapted your code to include functionality from Inflector0.11.4 which manifests itself as new Name enum types in addition to Name::Plain and Name::Numbered. Specifically:

• TitleCase - Adjective Noun
• CamelCase - adjectiveNoun
• ClassCase - AdjectiveNoun
• KebabCase - adjective-noun
• TrainCase - Adjective-Noun
• TableCase - adjective-noun
• SnakeCase - adjective_noun
• PascalCase - AdjectiveNoun
• SentenceCase - Adjective noun
• ScreamingSnakeCase - Adjective_Noun
