sensors: add humidity data to output of sensors command

Testing out a humidity sensor recently and was thinking the driver wasn't working somehow. Discovered instead that the driver works fine, but the sensors command was ignoring the humidity data.
This adds output of humidity data for sensors that support it.

Please consider applying it.

Thanks,
Iain

Please do, I could never find the time to review or test it :(
