Configure screenshots_dir in code, expose savedScreenshots

[tacman]

I want to use this awesome library to navigate my site and save screenshots, not necessarily as part of a functional test, but just a regular app.

final class AppScreenshotsCommand extends InvokableServiceCommand
{
    use PantherTestCaseTrait;
    use HasBrowser;

    public function __invoke(
        IO $io,
    ): void {
        $browser = $this->pantherBrowser(['screenshot_dir' => './screenshots']);
        $browser->visit('/')
            ->wait(4000) // wait for css??
            ->takeScreenshot('homepage.jpg');
        dd($browser->getSavedScreenshots());

How can I set the screenshot_dir in my console command? The above does not work, $options is different in that call.

Also, to get the screenshots at the end, I needed to add a getter to the PantherBrowser.php, would you accept a PR for that?

    public function getSavedScreenshots(): array
    {
        return $this->savedScreenshots;
    }

I am trying to use this to solve the problem of creating screenshots requiring authenticated users, e.g.
