* remove analog LED flicker

run SetRgbwPwm from main loop and with GetPixelColor(0) to get all effects using fade_out() working.

* correct unintended bitwise AND to logical AND

* Update analogLastShow

* new Arduino Core WaveForm library included

* new Arduino Core only for 8266

/*
esp8266_waveform - General purpose waveform generation and control,
supporting outputs on all pins in parallel.
Copyright (c) 2018 Earle F. Philhower, III. All rights reserved.
The core idea is to have a programmable waveform generator with a unique
high and low period (defined in microseconds). TIMER1 is set to 1-shot
mode and is always loaded with the time until the next edge of any live
waveforms.
Up to one waveform generator per pin supported.
Each waveform generator is synchronized to the ESP cycle counter, not the
timer. This allows for removing interrupt jitter and delay as the counter
always increments once per 80MHz clock. Changes to a waveform are
contiguous and only take effect on the next waveform transition,
allowing for smooth transitions.
This replaces older tone(), analogWrite(), and the Servo classes.
Everywhere in the code where "cycles" is used, it means ESP.getCycleTime()
cycles, not TIMER1 cycles (which may be 2 CPU clocks @ 160MHz).
