* 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
* Try to handle env and projenv in pylint
* Add deprecation comment about -ota envs

* 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

* Include Kogan Smarter Home plug with energy meter (KOGAN_SMARTER_HOME_PLUG_W_POW) into arduino.h

* Update platformio.ini to support Kogan Smarter Home plug with energy meter (KOGAN_SMARTER_HOME_PLUG_W_POW)

* Add Kogan Smarter Home plug with energy meter product image

* mention magic byte and flash mode in webui

* gzip magic

* make async ota at least usable. timeouts, show errors, try harder to find data after headers

* simplify setup and destruction

* cleanup class instantiations for ota and url

* handle default case of magicflashchipsize

* shorter

* blobs

* web: fix rfb node generator syntax, do not send as basic settings

* ha: allocate discovery object later

- use setOriginalsFromValues function right after elements had changed and
**only** with those elements
- add checkbox handling to setOriginalsFromValues to match hasChanged
- apply hasChanged after value is set to refresh originals after saving
- change parts that already set 'original' attribute manually

This was sort-of broken, because original attr never worked as intended. 
Also fix possible OOM for large WebUI images, since sending full config each time means that we need more memory to buffer and parse it.

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

This reverts commit 7efaaa8a80.

* 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.
