Reading sensor data

As a Hardware Developer I want the board to read the sensors including an analogue sensor for the steering angle, a digital hall sensor, a digital tie sensor, an odometer and the internal RTC (real-time clock) sensor so that I can use the data for further processing.

Acceptance criteria

1. The board reads the sensors if rising and falling odometer edge or at least every n millisecond. (n defined by config)
2. Reading the data returns the current status of all sensors.
