com.gluonhq.attach.position.Parameters has a bad constructor

[nlisker]

The Accuracy enum encapsulates predefined distance and time filters. Parameters can either take an Parameters (which it does), or take custom time and distance parameters. The problem is that there is a constructor that takes both an accuracy and time and distance parameters, making the accuracy meaningless.

I think that this constructor should be deprecated in favor of a (time, distance, background) constructor. getAccuracy() will return null in this case.
