Provide native CLI apps

[beatngu13]

Problem

We should provide native CLI apps (similar to what we wish to do for review) for the following reasons:

• No need to rely on installed JVM on the user's machine.
• Freely choose Java version for development.
• Faster startup time.
• Lower runtime memory overhead.

Solution

Picocli provides great support to create GraalVM native images:

GraalVM Native Image allows you to ahead-of-time compile Java code to a standalone executable, called a native image. The resulting executable includes the application, the libraries, and the JDK and does not require a separate Java VM to be installed. The generated native image has faster startup time and lower runtime memory overhead compared to a Java VM.
