Epic: Prepare taxonomy-lib for the 24.07 release.

To prepare taxonomy-lib for the 24.07 release, the following issues need to be addressed:

• A new height attribute HHT needs to be added to the parsing of attributes (#28 (closed)).
• Function is_valid_height_tag() needs to be adapted to correctly handle heights given as HHT (#28 (closed)).
• Function get_number_of_stories() needs to translate the total height of the building (given as HHT) into number of stories if these are not given as H, HBET or HEX (#29 (closed)).
• A new function to estimate the overlap of two height definitions needs to be added for better matching the building-class height attributes with the height attributes a building has (#30 (closed)).
• Implement occupancy translation for HAZUS taxonomy strings to the GEM taxonomy (#32 (closed)).
• Add the detailed occupancy tags (#33 (closed)).
• Implement a function to determine if two occupancy tags are compatible and which one is the more specific (#34 (closed)).

To start creating the 24.07 model:

• Create beta version (v2.0.0-beta.1)
