Add callback function for progress bar

[FlorianK13]

Something like this:

function runSimulation(steps, progressCallback) {
    for (let step = 0; step < steps; step++) {
        simulateStep(step);
        const progress = (step + 1) / steps * 100;
        progressCallback(progress);
    }
}

function updateProgressBar(progress) {
    console.log(`Progress: ${progress}%`); // Replace this with actual UI update logic
}

runSimulation(100, updateProgressBar);
