Thingspeak class improvement to answer Max's question:
why use a pointer when it can be a class member?
So now address parameter isn't a pointer anymore.

* comments, refactor naming

- add ltDimmerGPIO<index> & ltDimmerInv<index> to override / add to hardware configuration. Add pin defaults, mapped as GPIO_NONE. pwm_init() receives resulting GPIO mapping based on settings loader.
- remove bogus _light_channels variable, use this name for channel array instead (...which is vector and has size(). functions always use that value anyway)

* 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)

- use similar to relay & wifi, configuration through helper methods that
  use indexed defines
- clock cycles for led delay polling
- button mode defaults

* debug: log mode, allow to skip boot messages

* typo, fix warning about unhandled switch

* mention telnet wifiserver & reverse changes

* PIO: remove -ota envs, handle OTA condition in extra script
* Tweak ESPURNA_BOARD variable
* Support git and latest in ota script
* Handle ESPURNA_FLAGS too

* Add support for Kogan Smarter Home Plug With Energy Meter

Type: Power Plug
Board: Kogan Smarter Home Plug with Energy Meter
Build flag: KOGAN_SMARTER_HOME_PLUG_W_POW
Description: Power Plug with integrated Energy Meter
Baseboard: Tuya TYWE3S
Baseboard Data sheet: https://docs.tuya.com/docDetail?code=K8uhkbb1ihp8u

This LED strip is sold by ACTION in Germany and comes with a Tuya (TYWE3L) chip. It can be "freed" by using tuya-convert. It has (yet another) IR remote control that uses another set of codes. Which is added, too. The color codes are copies from SET 1 and 2.
I kind of think that they don't match my remote control but since i'm using my smart home system for controlling, i don't care enough to figure out the correct color codes.

The circuit board supports also a CW channel on PIN 5 (which is not used on by version), nevertheless I've added a comment in case anybody has a similar device with CW

* broker: drop REAL_TIME flag, use separate Broker entities

* influxdb: use async client, send data in batches

We have created a few dozens of devices, released as open-source hardware and
published the schematics to GitHub. We're planning to organize some small
(10-15 people) workshops on how to assemble, flash and configure these board.
