Debug logging, code cleanup, Mapped_Encoder, EEPROM, Encoder/Throttle Calibration, and more

Improvements to wheel.ino and Mapped_Encoder

• Debugging modes for outputting
• Arrays to iterate through buttons and LEDs with for loops
• Simplified logic
• Removed magic variables
• Removed unused variables
• Code now only waits for Serial to start in debugging mode
• Error avoidance for faulty received CAN messages
• Mapped_Encoder Library with its own class to make calibration and general usage of encoder and throttle easier
• Fixed floatMap, tested with math but not yet in code
• Calibration of encoder/throttle
  • helper functions
  • tolerance and number of trials
  • button combinations to enter calibration
• EEPROM reading/writing of encoder and throttle values via Preferences.h

Future plans

• Calibration logic for buttons and LEDs
• Sending logging data to shore
• Onshore testing
• CAN testing
• Water testing
• Calibration during crisis testing
• Hardware issues automatic detection and warning system
• Calibration integration with display
• Unit testing
