TODO: Update cooling-type argument parser to support optional air/water=0/1

[bjwyman]

The argument parsing for the phosphor-cooling-type application would ideally allow one to send in a parameter for --air or --water with an optional part that indicates what state of the pin indicates that condition:
Water is true if value of read is 1:
phosphor-cooling-type --dev=/dev/input/event0 --event=13 --water=1
Water is true if value of read is 0:
phosphor-cooling-type --dev=/dev/input/event0 --event=13 --water=0
...
