[DHT11] minor bugfixes, minor speed improvements

- fix timeout awaiting, add more time - move SKIP_LOW into dht11_measure_high_duration function to execute the function call before the PD11 line goes high, thus increasing the precision of signal length measurement
[DHT11] add testing code, currently not functional
