Kebab-case

Hi Typia,

I was looking at your notation transformers and noticed that it is not possible to convert kebab-case into a different case. I am working with an API that returns kebab-case data and dislike typing variable['x-y'] everytime I access something.
This library is able to freely convert between snake, camel en pascal, it would be awesome if it would include kebab-case.
I understand why you asked for code examples and examples on how it would work for feature requests, but I feel this feature is so easy to explain that I won't have to for it to make sense.
I also understand kebab-case is not as common as camel, snake and pascal, but it is out there!

hope this reaches you well and you find it important enough to implement.
Would be willing to give it a go myself if provided with some directions.
