```
The problem was `bim.enable_editing_material_set_item"` was trying to set `MaterialsData` profiles and wasn't able to set unnamed profile because `MaterialsData.profiles()` was discarding unnamed profiles (which is seems contradictory because `profiles()` is also handling unnamed profiles anyway).
- add check of OverallHeight and OverallWidth for creating openings for doors and windows;
- OverallHeight, OverallWidth update for all the occurences of the type for doors and windows;
- new tool.Ifc method - get_all_element_occurences
Prevents couple `pyrna_enum_to_py` warnings that occured using BIM Tool

API for docs works the same way as it worked for ifc2x3 and ifc4.
Besides changing `doc.py` and adding `.json` schemas added `ifc4x3dev_scrape_data_for_docs.py` (it's kind of hacky now and relies on `server.py` code from the further mentioned repo) that's used to parse some entities descriptions from https://github.com/buildingSMART/IFC4.3.x-development for later use in `doc.py`.
