DHT22/DHT11 humidity/temperature sensor usermod (#1719)

* DHT22/DHT11 humidity/temperature sensor usermod

* cleanup - don't report when usermod is auto-disabled since report isn't persistent

* track error count; retry once after error occurs

* for esp32, use esp32DHT library

* fix unreliable ESP32 readings by switching DHT library to https://github.com/alwynallan/DHT_nonblocking

* change default pin to Q2; don't burst readings if error occurs
