操作

Added support for WS2815B (#1800) 

* Introduced color mode, added support for WS2815B

* Revamped the sample

* Changed sample

* Fixed namespace

* Updated Readme

* Removed YouTube-Link

* Added copyright headers

* Removed color mode, added derivation of BitmapImageNeo3 for RGB-format

* Added new commented line that shows that the initialization of Ws2815b is identical to the other strips

* Broken up the menu output for better readability

* Moved properties (back) to protected const fields
