Maven plugin to generate schemas from data

There's a feature request
https://github.com/Kotlin/dataframe/discussions/717#discussioncomment-9665763
Gradle plugin has logic to simplify configuration for user and somewhat support variety of project layouts. It shouldn't be hard to develop a simple Maven plugin that requires explicit configuration for each schema and not tries to be smart
Thing that remains unclear to me is setting the dependency between this code generating task and Kotlin compile task

Start with the feature request in discussion 717 and the existing Gradle plugin logic. Define the Maven plugin's explicit per-schema configuration and investigate how its generation task should depend on the Kotlin compile task. Done means the plugin generates configured schemas and has the required compile-task dependency.
