compilation support for IDF4.4.3, plus compiling for ESP32-S3

- Updated ESP32 targets to use IDF 4.4.3 (thanks tasmota!)
- Fixed a compilation problem in ARTI (WLED_FS instead of LITTLEFS)

- Initial compilation support for ESP32-S3. Warning: there are still many problems to be solved before -S3 becomes usable!
- audioreactive: added #ifdef for features not yet supported on ESP32-S3
