Migration to Ettle

Strcase converts between snake_case, camelCase, kebab-case, and more!
Good test coverage and fast

Breaking change:

• camelCase - first word is lowercased, even if it's an initialism. What was previously camelCased as JSONresponse will now be jsonResponse to better support code generation use cases.
