* fixes multiple SHT3X sensor type bug
Important when multiple sensors are present at the same bus. Prior to this fix, multiple SHT3X sensor were detected, but not SHTC3 and SHT4X!
* Update xsns_14_sht3x.ino
Extends I²C address range to include SHT40-CD1B sensors with address 0x46.
* Update I2CDEVICES.md
* Show bus when multiple sensors at different busses
* Make bus number less intrusive
Only show bus number if two sensors or more are active at more than one bus.
* variable renamed
* cleanup
* fix typo
* fix another typo
* Harmonization and saving code size for ESP8266
Harmonization with xsns_09_bmp driver, saving code size for ESP8266
* fix string for webserver
* Display address only if more than one sensor present.
The conversion of humidity from raw value is different for the SHT4x
series. The fix implements the conversion as per datasheet. Also, the
raw value is now cast to float before division.
A SHT40 was not detected by the previous scheme of scanning the I2C
addresses and for each address probing for SHT3x and SHT4x immediately
one after the other. The SHT40 is succesfully detected when first
probing all adresses for SHT3x and then scanning all adresses again for
SHT4x. The fix implements this scheme. It was tested with SHTC3 and
SHT40 sensors.
