Implement HasAuthentication to be able to use authentication

[TareqK]

So after some debugging on a project, i found out that the driver doesn't implement HasAuthentication, which means that using basic authentication with selenide does not work - and might not work with mainline selenium(didn't test that). In all cases, implementing HasAuthentication solves this problem. I have a really dumb internal implementation, but having this built in would be nice.

Dumb workaround for basic authentication if someone is looking

public  class HtmlUnitDriverWithAuth extends HtmlUnitDriver implements HasAuthentication {

        public HtmlUnitDriverWithAuth() {
            super();
        }

        public HtmlUnitDriverWithAuth(BrowserVersion version) {
            super(version);
        }

        public HtmlUnitDriverWithAuth(boolean enableJavascript) {
            super(enableJavascript);
        }

        public HtmlUnitDriverWithAuth(BrowserVersion version, boolean enableJavascript) {
            super(version, enableJavascript);
        }

        public HtmlUnitDriverWithAuth(Capabilities capabilities) {
            super(capabilities);
        }

        public HtmlUnitDriverWithAuth(Capabilities desiredCapabilities, Capabilities requiredCapabilities) {
            super(desiredCapabilities, requiredCapabilities);
        }

        @Override
        public void register(Predicate<URI> whenThisMatches, Supplier<Credentials> useTheseCredentials) {
            Require.nonNull("Check to use to see how we should authenticate", whenThisMatches);
            Require.nonNull("Credentials to use when authenticating", useTheseCredentials);
            Credentials credentials = useTheseCredentials.get();
            if (credentials instanceof UsernameAndPassword usernameAndPassword) {
                String username = usernameAndPassword.username();
                String password = usernameAndPassword.password();
                String credsString = new StringBuilder(username).append(":").append(password).toString();
                String base64encodedUsernameAndPassword = new String(Base64.getEncoder().encode(credsString.getBytes()));
                this.getWebClient().addRequestHeader("Authorization", "Basic " + base64encodedUsernameAndPassword);
            }
        }

    }
