decodeSensorData, decodeValveData, decodeDelayData, decodeMiscData (#32)

* initial code to interpret valveDataArray

* Some additional comments on the valveDataArray decoding message

* Adds decodeSensorData, decodeValveData, decodeDelayData, decodeMiscData

* reverts unintended change to index.js

* Refactor / rename variables
	- renamed variables to better describe their use
	- created a helper function 'isValvePresent' to simplify code
	- changed while loop to for loop
