GetPumpStatus / SetPumpFlow commands (#28)

* added GetPumpStatus / SetPumpFlow commands

* Updated README.md with GetPumpStatus / SetPumpFlow information

* rename `setPointType` to `isRPMs`

* renamed val0 to pumpType and val1 to isRunning

* added `unknown command` case

* fixed lint error

* Renamed unknown values to pumpUnknown1 and pumpUnknown2

* renamed 30 to unknownCommand
