Currently Ws281xLedStrip#getBrightness() returns the int brightness which is set at the constructor.
When updating the brightness using Ws281xLedStrip#setBrightness(int) the ws2811_channel_t's brightness gets updated but never Ws281xLedStrip#brightness.
Altered the Ws281xLedStrip#setBrightness(int) to update the brightness so Ws281xLedStrip#getBrightness() returns the correct value.
