[Bugfix] - Function `get_number_of_stories` does not correctly identify a missing height attribute in the taxonomy data
Function get_number_of_stories should skip the determination of number of stories in case that the height attribute is not given in the taxonomy string. In the current version, the function skips the determination only in the case of a missing section in the _taxonomy_dict. However, this section missing is an indicator of a serious error and not of missing information about height. In the latter case, the section does exist but is empty.
Function get_number_of_stories therefore should take this into account and analyze the return of the get_section correctly.
