- Delaying and repeating i2c operation automatically when i2c interface is busy removed. User has to deal with concurrency using semaphores.

- GPIO_ID_PIN macros removed
- Soft reset mechanism of SHT3x does not work when sensor is in any measurement mode. Therefore, it does not abort initialization procedure anymore
- typos
- changes to use the same source code with ESP8266 (esp-open-rtos) and ESP32 (ESP-IDF)
