- 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)

There are examples for only one sensor and examples for two sensors.
To run examples with **one sensor**, just use GPIO5 (SCL) and GPIO4 (SDA) to connect to the SHT3x sensor's I2C interface.
To run examples with **one sensor**, just use GPIO14 (SCL) and GPIO13 (SDA) to connect to the SHT3x sensor's I2C interface.

If you want to run examples with **two sensors**, you could do this with only one bus and different I2C addresses or with two buses and the same or different I2C addresses. In later case, use GPIO14 (SCL) and GPIO12 (SDA) for the second bus to connect to the second SHT3x sensor's I2C interface.
