Compare different i2c temperature and humidity sensors (SHT2x, SHT3x, SHT85, ..)

Some high humidity test results
at RH ~75%

https://wiki.liutyi.info/display/ARDUINO/Test+5+v5+saturated+salt+solution

So the RH measurements are:

AHT10, HDC1080, AM2320 - above expected
HTU21d, BME280, BME680 - below expected
Si7021, SHT3x, most SHT2x, SHT85 - expected

t measurements (using SHT85 as a reference, since no other precision thermometers available)

BME280, BME680 - Above expected
