* rename platform rpi-pwm to rpi. remove original rpi platform
install symlink to bin folder
create effects folder for custom effects

* fix osx jobs evaluation

* - add rewrite time to serial leds
- rework adalight sketch

* add analog output

* adalight: add analog mode: last led

* tune adalight sketch to final state
move refresh code to leddevice base class, so every leddevice can use it
