[sensors] Refactor sensor sampling

See https://git.skywarder.eu/-/snippets/6.

• Add Sensor<T> and AbstractSensor, remove old Sensor.h
• Common interface also for sensors that use a FIFO
• Add base structs for sensor data, e.g. TemperatureData, PressureData ecc
• Refactor all sensors and entrypoint, eliminitating deprecated ones (out of production or those that can't be tested)
• Modify SensorManager to have a constant sensor map
• Integrate w/ cereal, see #82 (closed) (out of the scope of this issue, see #82 (closed) for future work)
• Implement sensor manager creation inside main() (see test entrypoints)
• Create auxiliary functions to enable a "global" 32-bit timer for accurate timestamps
