If calibration data is not found, full calibration will be performed. To ensure better RF performance,
it is recommend to set RF_calibration to ESP8266_PHY_FULL_CALIBRATION, otherwise the RF performance may become poor.
Full calibration needs 170 - 180ms.
Partial calibration needs 35 - 40ms.
No calibration needs 3.260 - 3.264ms.
