* Sensors: refactor configuration

- move sensor implementaion to the .ino,
  remove dependency undef / define from sensor files
- update test/build/sensor.h from SENSOR_SUPPORT
- allow to change sensor config variables externally
- `#include <...>` for global headers and libraries,
  fix relative path for math library

* add missing sns <-> i2c dependency

* ledrelay should return relay_none as default

* rollback to original test header

* include debug header when requested (relative)

So you can add more different PMS sensors.

And found DEBUG_MSG could not be used in the sensors header file.

1. Support PMS5003T/PMS5003ST;
2. Replace data reading method;
3. Remove PMS library dependency;
4. Support smart sleeping mode to extend the sensor’s lifetime.
