Fatal Error with CF7 Multi-Step Forms

Hi,

I’m getting a fatal error when using Turnstile with “Contact Form 7 Multi-Step Forms”. Validation is triggered before the form is submit, so the Turnstile Plugin is generating an error.

PHP Fatal error: Uncaught Error: Call to a member function get_posted_data() on null

The solution is pretty simple – in simple-cloudflare-turnstile/inc/contact-form-7.php, line 37 before getting the posted data, check if the Submission exists.

	$post = WPCF7_Submission::get_instance();
	if ( !empty( $post ) ) {
		$data = $post->get_posted_data();
		// the rest of the code...

It would be great if you could update the plugin to ensure compatibility with CF7 Multi-Step Forms.
