Experiment with java22 and Rust to monitor exceptions in a JVM

Running:
* Update the path to the rust lib (temp fix) in ExceptionLogger for your setup
* mvn clean install
* cd rustlib; cargo build
* create a minimal class in a separate project
```java
public class Main {
    public static void main(String[] args) throws Throwable {
        throw new Throwable();
    }
}
```
* run it with (adjust paths): 
``` bash
java22 -javaagent:$EXCEPTIONAL_PROJECT/exceptional/agent/target/exceptional-agent-1.0-SNAPSHOT.jar --enable-preview -classpath $YOUR_CLASSPATH Main
```
