Fix SimConnect_AddToDataDefinition to change default datumType to 4 and datumId to 0xFFFFFFFF

[bstudtma]

Fixed defaults for SimConnect_AddToDataDefinition

Summary

Fixed defaults so to allow multiple AddToDataDefinition

Before this changed, multiple calls to AddToDataDefinition would overwrite each other even if for a different var. This fix will allow multiple vars for a single definition.

Changes Made

Synced defaults with C:\MSFS 2024 SDK\SimConnect SDK\include\SimConnect.h

Additional Information

This is blocking a feature branch I'm working on to allow dynamic structures.

This is needed for a bigger change I was working on... which you can check out here:

https://github.com/bstudtma/SimConnect.NET/blob/add-dynamic-structures/MyApp/Program.cs

Was trying to add support for getting structures dynamically and ran into this bug. The bug causes a single var to be returned even if multiple were added to the definition.
