🚀 feat(types): add string manipulation utility types

✨ feat(index.ts): add string manipulation utility functions
The `types.ts` file contains new types that allow for string manipulation utilities. The `index.ts` file contains new functions that allow for splitting strings by case, converting strings to PascalCase and CamelCase, and joining strings by case. These utilities can be used to improve the readability and consistency of code.
