mumpf 164bf59166
added alternative GroupObject with less mangagement footprint (#125)
* corrected float with DPT9

* Switch Programming-LED also via Bus/ETS

* Again: Prog-LED switchable from bus/ETS

* DPT16 (to bus) implemented

* - added SMALL_GROUPOBJECT

* - added knx-demo-small-go example
- added config.h option (commented)
- changed platformio-ci.ini with -DSMALL_GROUPOBJECT
- changed plantformio.ini with tested -DSMALL_GROUPOBJECT

* - removed duplicate files
