[AsyncAPI] Transform snake_case to camelCase

[arthureberledev]

Our schemas include properties written in snake_case currently resulting in some awkward getter and setter names like for example getClient_id and getUser_adress.

It would be awesome if the generator could automatically transform these names to camelCase. I believe the official OpenAPI generator is being able to do that.

Can you provide an example for that case?
