feat(overheat): Add overheat indicator lamps for oil, water, water_aux, and engine

Browse Source 
- Add engine_max_temp and engine_is_hot fields to heat_data structure
- Add EngineMaxTemperature field extraction from .fiz files
- Add engine overheat check comparing Ts with engine_max_temp
- Add four new overheat lamp indicators:
  - i-oil_overheat
  - i-water_overheat
  - i-wateraux_overheat
  - i-engine_overheat
- Add lamp update logic to turn on/off based on is_hot flags
- Add lamp initialization in clear_cab_controls()

This implements issue #77 - overheat lamps for diesel engines.

The lamps will turn on when:
- Oil temperature exceeds OilMaxTemperature
- Water temperature exceeds WaterMaxTemperature
- Auxiliary water temperature exceeds WaterAuxMaxTemperature
- Engine temperature exceeds EngineMaxTemperature

Each check includes 8-degree hysteresis to prevent rapid on/off cycling.
