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.

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.

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.
