Proposed change

• Position will be updated only if the endpoint has the position attributes
• Changed the attribute in which is based the position from CurrentPositionLiftPercentage and CurrentPositionTiltPercentage to CurrentPositionLiftPercent100ths and CurrentPositionTiltPercent100ths
  • This change has been done because at the matter specs, the old ones are optional and the new ones are mandatory.
  • Position is rounded to the ceiling (in fact is rounded to the floor but then is subtracted to 100, so it is like is rounded to the ceiling) because 0.01% open is near to be closed, but it stills open.
• Added test and multiple fixtures that contains different features to test both PRs
