Add functions SetPrimaryPartCFrame and PivotTo()

[forveined]

I tried using these functions and they arent supported by lune it seems

[filiptibell]

Lune only supports basic instance methods and generally does not add class-specific ones such as SetPrimaryPartCFrame and PivotTo - it is mentioned in the docs here that this is not something we will try to do. For these methods specifically you can get the same functionality by manually getting and setting CFrame properties on parts in your model.
