The sncast feature of --arguments is a very powerful and convenient tool to serialize complex types in Cairo.
Sometimes, the serialized version is needed, for use in other tools, explorers etc.

Would be great if there is a feature of sncast serizlize that takes the same input as --arguments of invoke and call, but does not produce any on-chain activity, and simply prints out the serialized calldata felts to the terminal
