delete method
Deletes the assignment between a location and a location list.
Request parameters:
advertiserId - Required. The ID of the DV360 advertiser to which the
location list belongs.
locationListId - Required. The ID of the location list to which this
assignment is assigned.
assignedLocationId - Required. The ID of the assigned location to
delete.
Value must have pattern ^\[^/\]+$.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Empty.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.

      commons.escapeVariable('$advertiserId') +
      '/locationLists/' +
      commons.escapeVariable('$locationListId') +
      '/assignedLocations/' +
      core.Uri.encodeFull('$assignedLocationId');
  final response_ = await _requester.request(
    url_,
    'DELETE',
    queryParams: queryParams_,
