LuaState with "user context" for passing references to C# LuaFunction

[CodeSmile-0000011110110111]

More than once I would have found it useful for some C#-specific "userdata" object attached to the LuaState itself (unavailable to Lua).

I noticed there is a commented AdditionalContext property in LuaFunctionExecutionContext:

//public object? AdditionalContext { get; init; }

Is this planned to be added?

When Lua calls a C# method, the LuaFunction context is "static" so it's difficult to call into the C# API.
My use-case is an object factory which instantiates the correct Lua wrapper for component based on the component's C# type.

Right now I just have my factory in the global Lua state and need to read it from the Environment table:

var component = AddComponent(type);

var factory = context.State.Environment[nameof(LuaObjectFactory)].Read<LuaObjectFactory>();

var luaValue = factory.CreateLuaInstance(component);
context.Return(luaValue);

Would be nice if I could hide that implementation detail (factory) and to avoid risking that factory getting erased by a simple assignment. Like with the AdditionalContext property for instance:

var component = AddComponent(type);

var factory = ((MyStateData)context.State.AdditionalContext).Factory;

var luaValue = factory.CreateLuaInstance(component);
context.Return(luaValue);

PS: I would call it UserContext, in-line with UserData.
