Feature: Kebab Case

[Ilyes512]

A KebabCase functions. I think it should behave exactly like snakecase accept that _ becomes -.

It's also requested on Masterminds/sprig#113.

The rule of transform camel case to kebab case is the same as the rule described in #1 camel case to snake case.

• SomeWords => some-words
• HTTPServer => http-server
• NoHTTPS => no-https
• HTTP2XX => http-2xx
• http2xx => http-2xx
• HTTP20xOK => http-20x-ok
