Use correct field separator in keywords.txt
...
The Arduino IDE requires the use of a single true tab separator between the keyword name and identifier. When spaces are used rather than a true tab the keyword is not highlighted.

Modified read speed
...
Reduced delay times from 250ms and 20ms to 1ms. This was done in accordance with the datasheet. E.G. no where does it say you need to wait 250ms or 20ms. It does say to set the line high for a minimum of 1ms (the second delay). This has been tested and is working in my of my projects

Use INPUT_PULLUP
...
Previously, the mode was configured to INPUT and then written HIGH,
which works on AVR but isn't very portable. Instead, this uses the
INPUT_PULLUP pin mode (available since Arduino 1.0.1) which is portable.

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.

Clean up two-second interval check
...
There was some handling of millis() overflow that is not needed.
Standard unsigned subtraction and wraparound already works as expected,
so this extra check can be removed (it even hurts, since it introduces 2
seconds after a wraparound where no new data will be read, even if it
could otherwise happen).
Also, this prevents calling millis() a second time, since its value is
already known.

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.
