Support built-in case conversions from https://github.com/clj-commons/camel-snake-kebab #93
Description
I find it very common to convert keywords to kebab case when working with EDN from JSON.
Understand it's not too hard to do so with 3 extra lines of deps pulling in bb, in order to access the CSK fns. But it'd be very nice to have those fns as options for -k. The lib is tiny after all.
Happy to submit a PR if agreed.
