Livery fixes

Hey, seeing as the A321 was just updated I was hoping that it would be a good time to re-address this.

Hi, we got different teams, modeling/animation team, livery team, coding team.

So they work separately and the things that are priority will be released as they go. Eventually we might return to livers on the 321neo

Hello, good afternoon. I was wondering if it is possible to add the following two things to the VivaAerobus a321 livery for the Xbox version.

- The black mask on the windshield.
- The "Viva" text on the inside of the winglets.

Here is a picture of the livery for reference:
