Feature: Clean up topics and schema subjects

[chuck-alt-delete]

Is your feature request related to a problem? Please describe.

My schema file might have a dozen Kafka topics and it’s a little cumbersome to delete all of those if I want to clean up.

Describe the solution you'd like

Add a --clean option that takes all the topics in the input schema file and deletes them from kafka. If using schema registry, also delete the associated schema subjects.
