No class ExtendedCommonRoadFileWriter in opendrive2lanlet.io 1.1.0

Dear all,

I am a master student of Xiao and want to use the interface for my thesis.

I tried the minimal example for checking the installation. But I got this error from sumo2cr/maps/util:

ImportError: cannot import name 'ExtendedCommonRoadFileWriter'

Corresponding to line 13 in sumo2cr/maps/util: from opendrive2lanelet.io.extended_file_writer import ExtendedCommonRoadFileWriter

I looked at the current opendrive2lanlet.io version 1.1.0, but it has this class commented out.

Can I just comment it in? Was it replaced by regular CommonRoadFileWriter from the commonroad package? Or is there a new version?

Thanks in advance.
