You can register one or more datapoints with this factory and query them based on the main number and sub number.
This class follows the singleton design pattern. Only one instance of this class can be created and its reference can be fetched from the instance () 方法。
The KNX datapoint types are identified by a 16-bit main number and a 16-bit sub number.

Returns a new instance of a QKnxDatapointType subclass. The instantiation of the subclass depends on the mainType and subType given as arguments to this function.
注意： The ownership of the created object remains with the programmer.
