Parses a PDU string into an instance of a PDU object (Deliver, Submit, or Report).
This function is a high-level entry point for parsing PDU strings into their corresponding PDU object types
based on the detected PDU type within the provided string. It handles the initial parsing steps common to all PDU types,
such as the Service Center Address (SCA) and PDU type determination, and then delegates to specific parsing functions
based on the PDU type.
