Hi all,
This is to add automatically selection of I2C addresses 0x76 and 0x77 for BME280, BME680 and BMP280.
Many BME280, BME680 and BMP280 mix up the default I2C address 0x76 and 0x77 for the sensors.
Logic: If the address is not fixed, then try both 0x76 and 0x77.

This will avoid soldering to fix the address to 0x76 in MeshCore.
Tested working for a while.

This is one of the issues #2714
