Add new features to HUD

[vinle0]

• Reticle sight, to determine where the player should aim
• Flywheel On, indicate whether we are actively shooting. A helpful feature since there can be a jam within the agitator
• Beyblade Indicator, whether standard is currently spinning
• Chassis direction, icon of the turret relative to the chassis; some lines indicating the boundaries of the standard

Would also need to allow for modular design, where we can add and manage additional HUD elements in the future

This code needs to be tested on robot hardware before it can be merged.
Once everything is confirmed to be working, please remove the needs-testing label.

Currently, there is an abstract class for the basic framework of the graphics. Any specialized graphics will inherit this class; there's some problem with the abstract class pointers in the client subsystem that will need fixing.
