Expose _unitOfMeasure

[kubawolanin]

Hi! Currently in the code I see just one reference to _unitOfMeasure:

    if self.is_undefined(self._raw_state):
      self._state = None
    else:
      self._state, self._unitOfMeasure = self._parse_rest(self._raw_state)

The property is not initiated and it's not accessible from the API.

Would be great to get it separately.

Best regards and thank you for your hard work!

Hi thanks! ... I fixed the implementation and exposed the value returned by the API.

item.unit_of_measure
