CHANGELOG
2016-05-28 Initial beta release
2016-06-03 Code cleanup, minor improvements, new modes
2016-06-04 2 new fx, fixed setColor (now also resets _mode_color)
2017-02-02 added external trigger functionality (e.g. for sound-to-light)
2017-02-02 removed "blackout" on mode, speed or color-change
2017-09-26 implemented segment and reverse features
2017-11-16 changed speed calc, reduced memory footprint
2018-02-24 added hooks for user created custom effects
Modified for WLED
Modified heavily for WLED
