update BLE library for ESP32 env compatibility

with the last version of ESP32 arduino env it is not possible to compile on ESP32, we get "missing gatt_api.h" ERROR. So as to avoid that we need to use the last version of the nkolban library for BLE 0.4.16

lib/ESP32_BLE_Arduino/src/BLECharacteristic.h
