Added Wordwall provider

[azeos]

Hi, First of all, thanks for this package.

I've just added wordwall.net provider to our platform. Are you accepting PR?

Documentation

/**
 * Wordwall Provider
 * @link https://wordwall.net/
 * @link https://wordwall.net/about/oembed
 */
class Wordwall extends ProviderAdapter implements ProviderInterface
{
    /** inline {@inheritdoc} */
    protected $endpoint = 'https://wordwall.net/api/oembed/?format=json';

    /** inline {@inheritdoc} */
    protected static $hosts = [
        'wordwall.net'
    ];

    /** inline {@inheritdoc} */
    protected $httpsSupport = true;

    /** inline {@inheritdoc} */
    public function validateUrl(Url $url)
    {
        return (bool) (preg_match('~wordwall\.net/(?:[^/]+/)?(?:resource|play)/.*+~i', (string) $url));
    }

    /** inline {@inheritdoc} */
    public function normalizeUrl(Url $url)
    {
        $url->convertToHttps();
        $url->removeQueryString();

        return $url;
    }

}

Hi @azeos Thank you very much for the code! If you want, you can add a PR with Tests and register it to the 02-providers.md file inside the documentation folder. Let me know if you have time to do it or I will add it myself next week.
