Feature/color objects color command (#302)

* added BACnetColorCommand and BACnetxyColor encoding and unit testing

* Added Color object and unit testing.

* Added Color Temperature object and Unit test

* Fix BVLC unit test warning.

* add port Makefile for extra types

* added RGB to and from CIE xy utility in sys folder, and add unit tests.

* added cmake-win32 target

* Change RP and RPM to use known property decoder.

Add color object RP and RPM decoding and printing
Fix RPM print for new reserved range above 4194303
Change default protocol-revision to 24 for Color object

* Integrate Color and Color Temperature objects into demo apps
