Type library missing LdrLoadDll in ntdll

[xusheng6]

>>> type_lib = bv.platform.get_type_libraries_by_name('ntdll.dll')[0]
>>> bv.import_library_object('LdrLoadDll', type_lib)

^ this returns None

This might be expected since iirc LdrLoadDll is not a documented API and might be missing from our data sources for the type library. Still, I am creating this issue to keep track of it since it would still be nice to have it

Just a note that it might be worth trying to integrate https://github.com/winsiderss/systeminformer/tree/master/phnt/include into our generator pipeline to include some of the APIs that aren't officially documented.
