Cannot read inherited members via TypedDataAccessor

Version and Platform (required):

• Binary Ninja Version: 4.0.4911
• OS: macOS
• OS Version: 14
• CPU Architecture: M1

Bug Description:
When using the python api, trying to access inherited structure fields like normal fields fails.

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

1. Open this binary with pdb: animals.exe.zip
2. At 0x409be0 (Bear::vftable) create a data variable with type struct Bear::VTable
3. Run Python: current_data_var["roar"]
4. Observe success
5. Run Python: current_data_var["describe"]
6. Observe error

Expected Behavior:
I expected all of the members (even the inherited ones) to be usable via the accessor

Additional Information:
Need support for looking up inherited members by name, also what should it return? Just the member or also all of the inherited information? Need to see StructureType.__getitem__ as well as TypedDataAccessor.

Start with StructureType.getitem and TypedDataAccessor, using the supplied animals.exe reproduction and the current_data_var["roar"]/current_data_var["describe"] accesses as the entry points. Determine how inherited members should be represented, then verify that inherited names such as "describe" are accessible through the TypedDataAccessor without breaking direct members.
