Removed all BLE code. It is not usefull in this application.

Version 0.4.1 Measure internal chip temperature, range -10 to 80. Result available in mqtt json payload.

Added basic BLE code.

Preparations for BLE GATT. Added extra time after INA219 is powered on before measurement. Reduced LEDC frequency to 60 Hz, that makes the LED lights less nervous. Hardware mod on output 4, now needs external pulldown resistor.

Added INA219 power save mode again, it works now. Don't measure shunt voltage and current, just the shunt voltage and calculate the current.

Reduced I2C master speed from 400 to 100 Khz. Hope to get power-on init for BMP280 more reliable. Added warnings for I2C devices that are missing. Some logmessages reduced to debug log messages. Added extra 10 mSec delays before read shunt voltage in the INA219 task. Removed and reduced log levels in the MQTT task. Show received data events. Remove WiFi total time debug logging, it's ok now.

Shorter delays during wifi connect timeout. Some code cleanup in the main state table. Report WiFi TX power during init. Removed SSID from WIFI_State because it wasn't used.

Decreased WiFi transmit level to 13. Level 15 is unstable, skip 14 just to be sure. It seems to be the bad designed antenna circuit on the ESP32-C3 Lolin v2.1.0 board. The board also benefits from a ground plane connected to the shield of the USB connector. The final implementation needs an external antenna anyway so the onboard antenna will go away. In the meanwhile, the wifi task is now more robust. Also, in testing mode there is no battery alarm, only when building for production.
