Ws2812spi and sk6812rgbw have wrong default rate (#221)

Browse Source 
* Changed default baud rate in schema for ws2812spi and sk6812spi

* now sets the default baud_rate speed to 2800000 if omitted.
Previously it used the ProviderSPI default which was 1000000 and guaranteed not to work

* Added warnings if the SPI baud rate is likely out of range
Added some debug statements to ProviderSpi
