Recursively transforms keys of maps. The root data structure can be a Map or a List.

Keys are passed to a user-provided transformation function that accepts a string and returns a transformed string.

Atom map keys are converted to strings before being passed to the transform function.

See JsonTransform.Transformers for a list of included transformation functions. You are also free to provide your own.
