dht: Fix sensor reading from DHT22 (#926)
* dht: Fix sensor reading from DHT22 (#239)

Looking at the datasheet for DHT22, it claims to need a delay of 18ms, not
800us. Change to use the same delay as DHT11. Tested working with NodeMCUv3
and DHT22 sensor with board with built-in resistor.

* dht: Add model DHT22_TYPE2 with 2ms delay instead of 0.8ms

The model DHT22_TYPE2 is exactly the same as DHT22, but uses a different
delay.

* dht: Fix bogus negative temperature reading on DHT22_TYPE2

The workaround for negative numbers associated with DHT22s can be skipped
on these sensors.
