v1.4.0 to add support to ESP32-C3

### Releases v1.4.0

1. Add **LittleFS and SPIFFS** support to new **ESP32-S2** boards (**Arduino ESP32C3_DEV**). Check [HOWTO Install esp32 core for ESP32-S2 (Saola, AI-Thinker ESP-12K) and ESP32-C3 boards into Arduino IDE](#howto-install-esp32-core-for-esp32-s2-saola-ai-thinker-esp-12k-and-esp32-c3-boards-into-arduino-ide).
2. Add **EEPROM and SPIFFS** support to new **ESP32-C3** boards (**Arduino ESP32C3_DEV**). Check [HOWTO Install esp32 core for ESP32-S2 (Saola, AI-Thinker ESP-12K) and ESP32-C3 boards into Arduino IDE](#howto-install-esp32-core-for-esp32-s2-saola-ai-thinker-esp-12k-and-esp32-c3-boards-into-arduino-ide).
