* 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fix compile * set colororder back to static * in remote: using correction is the same as using temperature - correction is obsolete, command not delete atm for compat reasons
