operator missing in datex2_taubert

[ThorstenFroehlinghaus]

https://api.mobidata-bw.de/ocpdb/api/ocpi/3.0/locations?source_uid=datex2_taubert does not contain operator information. although it is contained in the Mobilithek XML file:

								"operator": {
									"afacAnOrganisation": {
										"name": {
											"values": [
												{
													"lang": "de",
													"value": "next step mobility GmbH"
												}
											]
										},

Solved by #233 . Reason was that Taubert assigned the operator to the station, not to the location.
