v 1.3.3 - UV Index correction

/*

• v1.3.3

•  1. Corrected error with readUV casting an int result / 100. Now casting that operation as a float. I was always receiving a UVIndex of 0
  

• v1.3.2

•  1. I2C OLED diagnostics added (if needed)
  

v1.3.1

Minor correction on version #define error and now reports rssi topic. If no WiFi connection can be established, the system will give up and sleep. WDT reset is avoided.

v1.3 minor stability and operational tweaks

1. See changelog in weather.ino for details
2. RSSI topic added
3. 24h rainfall accumulation error fixed
4. uv.begin added (error correction) - addressed in 1.2.2 also
5. Clear summary of sensor status in console output when running

Minor bug fixes

1. uv.begin missing, now corrected
2. MQTT is now an app choice, not an afterthought

Minor correction for use of ESP32 deep sleep

#include "esp_deep_sleep.h" is not needed and not part of the ESP32 software package.

Formal packaging of 1.2

not a "new" release, just forgot to formalize the v1.2 release from the fall of 2021.
