Add Arm and Drive Precision Mode

[Supernova1114]

While a button is pressed on the gamepad, reduce maximum motor speed. This enables precise control of the arm and drive system.

Add Arm and Drive Precision Mode

(purple controller is drive, green controller is arm)

Button Descriptions

• right bumper: safety button for drive
• right trigger: go button for drive
• left bumper: nothing
• left trigger: nothing for arm, something for drive

PLAN - left bumper for precision button

Notes on gamepad_input.py

• deadzone - the area around thumb stick controller that doesn't respond to movement
  • the higher the deadzone, the larger the area of the deadzone (need to move the joystick a farther distance to be able to move)

Justine implemented precision mode for arm system. She will be working on the same for the drive system.
