The binary field in signal pack types can be removed #596
Description
Current Status
When sending a DartSignal or RustSignal, an empty binary field is included. This is not really needed, unlike DartSignalBinary or RustSignalBinary.
Describe the Task
Introducing new struct and classes, DartSignalBinaryPack and RustSignalBinaryPack. DartSignal and RustSignal won't need the binary field anymore.
Additional Context
The current implementation was influenced by older Rinf versions, and it can be made more efficient. However, #565 should be resolved first for backward compatibility.
