redPanther 36b4d072c5 common ledbuffer for color transform (#77)
* common ledbuffer for color transform

hyperion class uses a common buffer for all operations on ledColors got from muxer
all color transforms uses new ledBuffer instead of making copies of ledbuffer

other fixes:
fix compile bug in profiler
update doxygen config

* migrate logging for color transform classes

* prepare new logger in hyperion class

* implement hwledcount

* Update Hyperion.cpp

Fix off color

* remove ledscount equivalent from apa102
migrate logging in hyperion.cpp
remove unused and duuplicate colorcorrection - but same is available through tempertature

* remove colorcorrection completly
fix compile

* set colororder back to static

* in remote: using correction is the same as using temperature - correction is obsolete, command not delete atm for compat reasons
