[untested] added Sk6822 led device support (#397)

Browse Source 
* Adding support for sk6822 timing
This isnt complete, but should be a good starting point for others to learn from.

1) Here is where the led device source is located:

cd libsrc/leddevice

2) Find the files that need changing:

root@loungepi:libsrc/leddevice# grep -ri 2812spi *
CMakeLists.txt:         ${CURRENT_SOURCE_DIR}/LedDeviceWs2812SPI.h
CMakeLists.txt:         ${CURRENT_SOURCE_DIR}/LedDeviceWs2812SPI.cpp
LedDeviceFactory.cpp:   #include "LedDeviceWs2812SPI.h"
LedDeviceFactory.cpp:   REGISTER(Ws2812SPI);
LedDeviceSchemas.qrc:           <file alias="schema-ws2812spi">schemas/schema-ws2812spi.json</file>
LedDeviceWs2812SPI.cpp:#include "LedDeviceWs2812SPI.h"
LedDeviceWs2812SPI.cpp:LedDeviceWs2812SPI::LedDeviceWs2812SPI(const QJsonObject &deviceConfig)
LedDeviceWs2812SPI.cpp:LedDevice* LedDeviceWs2812SPI::construct(const QJsonObject &deviceConfig)
LedDeviceWs2812SPI.cpp: return new LedDeviceWs2812SPI(deviceConfig);
LedDeviceWs2812SPI.cpp:bool LedDeviceWs2812SPI::init(const QJsonObject &deviceConfig)
LedDeviceWs2812SPI.cpp:int LedDeviceWs2812SPI::write(const std::vector<ColorRgb> &ledValues)
LedDeviceWs2812SPI.h:class LedDeviceWs2812SPI : public ProviderSpi
LedDeviceWs2812SPI.h:   LedDeviceWs2812SPI(const QJsonObject &deviceConfig);

3) Copy the existing files as a starting point:

cp LedDeviceWs2812SPI.cpp LedDeviceSk6822SPI.cpp
cp LedDeviceWs2812SPI.h LedDeviceSk6822SPI.h
cp schemas/schema-ws2812spi.json schemas/schema-sk6822spi.json

4) Do some search and replacing:

:%s/Ws2812SPI/Sk6822SPI/g

5) edit the other files (see the diffs in this commit)

* Added wait time and reset time

* Fixed up debugging output and commented it out.
