Update for 2022 or later

[TheHarmonicRealm]

Not high priority at all — the robot still works fine with the code currently on it — but something that should probably be done eventually is updating the project for 2022/later years and fixing any bugs so it can be compiled and the robot still works e.g. if the roboRIO breaks and needs to get replaced. Even the code from 2020 already doesn't build without modification; we should handle this before Atlas breaking would become a major problem.
