models/cli_configs/setup_versions_cli_config library

The setup_versions command manages versioned Inno Setup installations.

Inno_bundle can test against multiple Inno Setup versions, each installed into its own folder under the package's managed versions directory (~/.inno_bundle/versions). This class models the arguments that drive that setup: which versions to install and the output framing. See the bin/setup_versions.dart entry point for how these are consumed.
