45a20da301 Shrink DHT::data to 5 bytes
There's only 5 bytes of data being transferred (2x2 bytes of data, 1
byte checksum), so no need to keep a useless byte.

5973929e63 Remove the firstreading variable
By cleverly setting _lastreadtime in begin() to make sure that it looks
like the last read was alrady 2000 ms ago, even on startup when millis()
still returns 0, there is no longer a need to keep a separate
firstreading variable, saving a byte of memory and a bit of code.

04905bc5cd Add force parameter to read methods
This allows forcing a read, even if the previous read was less than 2
seconds ago. This is useful in cases where the millis() timer is not
reliable, such as when sleeping. In this case, it is up to the caller to
ensure that at least 2 seconds elapse between calls with force set to
true.

ad73fab623 Support for non 16mhz devices
Added constructor parameter to allow for different timing needs. It has
the a default value of 6 which is the original value, so it should be
backwards compatible

fca71323bd Prevent dht.h being imported multiple times
Added a basic #ifndef DHT_H to the dht.h file so that if you have a
larger program and want to access the sensor from a different file, you
don't import it twice.
