* Update WebSocket library * Update SSDP library * Update TFT_eSPI library * Update EspLuaEngine library * Update SDFat library * Change to pioarduino * Make ESP3DMessageFIFO and ESP3DMessage more thread safe * Fix sanity checks for BT * Add some C6 support * Refactor ethernet code * Split Ethernet Sta / WiFi sta ESP Commands and settings * Simplify wait and wdtFeed code * Set C3 with 4MB by default in platformio.ini * Apply Disable brown out only on ESP32 to avoid crash e.g:ESP32S3 * Add missing entries in platformio.ini
