Add a Graphic to the Pre-Match Screens Indicating the Responsibilities of a Scoring Referee

**Is your feature request related to a problem? Please describe.**
At our Robot in 30 Hours scrimmage, we had incidents of scoring referees scoring the wrong alliance.

**Describe the solution you'd like**
Add a graphic to the pre-match screens for scoring referees that indicate:
- What alliance's goal you're scoring
- What alliance's auto leave you're scoring
- What alliance's base you're scoring

**Describe alternatives you've considered**
Training could help, but this would be a more effective engineering solution.
