Added the RMT/addr LED blink to the example and more detailed README.md Moved component/led_strip to common_components Added missing README file to common_components/led_strip README file update Makefile and Kconfig fixed for led_strip component Fixing end-of-line on main/blink.c Component updated to handle multiple instances Added note on the RMT channel number (ESP32 and ESP32-S2) Removed components folder from rmt/led_strip example and README updated Changed the led_strip_denit function and added ESP32-C3 RMT info on channel configuration Updates on README, Kconfig default settings and configure_led() function added
