* ADC_VCC is not macro

* In esp.h ADC_VCC and ADC_TOUT is not macro, so define macro.

* ADC_VCC and ADC_TOUT fixes in utils.ino and sensors.h

* Adding support for I2C temperature and humidity sensor HDC1080 / 831R

* Added HDC1080 to test\build\sensor.h and arduino.h

* added brackets

* Revert ADC_MODE_VALUE to initial values

* Eof newline

- Update sensor classes to support a generic way to store energy values
- Update sensor conversion code to deal with units and not magnitudes
- Add magnitude<->unit for sensors, generic way of defining used unit. Convert from sensor magnitude unit to the one used for display.
- Reset energy value based on index through external means (MQTT, HTTP)
- Rework energy timestamping, update webui with 'last saved' value

While this solves the energy conversion issues and we are finally seeing the real value, what I don't really like:
- KilowattHour and WattHour are separate enum tags, thus sort-of are different types altogether
- Conversion code in Energy object should probably use some generic 'ratio' calculation? (https://en.cppreference.com/w/cpp/numeric/ratio/ratio)
- We are still using runtime checks to do calculations and depend that sensor outputs only one specific value type.

Consider this a fix for energy display / storage and preliminary work on sensor.ino
Further sensor refactoring... soon.

* Add support for read PIO-A of DS2406

* Verify reset() reseult

* 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)

* experimental: refactor get/set/del/hasSetting

Operating specifications / Communication and signal

"Data-bus's free status is high voltage level. When communication
between MCU and DHT22 begin, program of MCU will transform data-bus's
voltage level from high to low level and this process must beyond at least
**1ms** to ensure DHT22 could detect MCU's signal, then MCU will wait 20-40us for
DHT22's response."
